According to Garland (2013), there is skepticism about mindfulness as an effective intervention. Often, because of its philosophical roots in Buddhism, practitioners and scholars equate mindfulness wi

Mindfulness Research in Social Work:

Conceptual and Methodological Recommendations Eric L. Garland Mindfulness refers to a set of practices as well as the psychological state and trait produced by such practices. The state, trait, and practice of mindfulness may be broadly characterized by a present-oriented, nonjudgmental awareness of cognitions, emotions, sensations, and perceptions withoutfixation on thoughts of past or future. Research on mindfulness has proliferated over the past decade. Given the explosion of scientific interest in this topic, mindfulness-based therapies are attracting the attention of clinical social workers, who seek to implement these interventions in numerous practice settings. Concomitantly, research on mindfulness is now falling within the scope and purview of social work scholars. In response to the growing interest in mindfulness within academic social work, the present article outlines six conceptual and methodological recommendations for the conduct of future empirical studies on mindfulness. These recommendations have practical importance for advancing mindfulness research within and beyond social work. KEY WORDS: evidence-based practice; meditation; mindfulness; randomized controlled trial; research methods M indfulness is linked with a set of cross- cultural principles and practices origi- nating in Asia more than 2,500 years ago that have parallel manifestations in numerous cultures around the world. With regard to its cur- rent academic usage, mindfulness refers to a psycho- logical phenomenon that is now being studied for its relevance to mental and physical health infields such as medicine, psychology, and neuroscience.

Across thesefields, there is a growing body of litera- ture that attests to the efficacy of mindfulness-based therapies for a wide range of biobehavioral disorders.

According to a search of PubMed and CRISP data- bases conducted on October 4, 2009, there were 1,614 peer-reviewed journal articles on mindfulness published in the scientific literature and 320 research grants on mindfulness funded by the National Insti- tutes of Health between 1998 and 2009. Indeed, there is mounting empirical evidence of the role of mindfulness in reducing stress and improving clinical outcomes across diverse conditions such as depres- sion (Teasdale et al., 2002), relationship difficulties (Carson, Carson, Gil, & Baucom, 2004), irritable bowel syndrome (Gaylord et al., 2011), crimi- nal recidivism (Himelstein, 2011), chronic pain (Rosenzweig et al., 2010), and addiction (Bowen et al., 2006;Garland, Gaylord, Boettiger, & Howard,2010). Consequently, mindfulness-based interven- tions are becoming well-regarded for their therapeu- tic promise, as evidenced by recent publications in mainstream, respected academic outlets, such as the JournaloftheAmericanMedicalAssociation(for exam- ple,Ludwig & Kabat-Zinn, 2008).

Given this burgeoning interest, mindfulness- based interventions are attracting the attention of clinical social workers who are increasingly imple- menting these treatments across diverse domains of practice. Concomitantly, research on mindfulness is now falling under the purview of social work scholars, many of whom seek to determine the comparative effectiveness of mindfulness-based interventions and apply the construct of mindful- ness to theories and models of social work practice.

In response to the growing interest in mindfulness within academic social work, this article outlines six conceptual and methodological recommenda- tions for the conduct of future empirical research on mindfulness. INCREASE PRECISION IN OPERATIONALIZATION OF THE CONSTRUCT OF MINDFULNESS To advance anyfield of scholarship, the precise operationalization of constructs is a necessaryfirst doi: 10.1093/swr/svt038 © 2013 National Association of Social Workers 439 step. Without such precision, empirical investiga- tions of putatively identical phenomena may result in widely divergent correlations between constru- cts of interest and inconsistent clinical outcomes across studies. Ultimately, imprecise operationaliza- tion of constructs presents a severe threat to validity that can undermine the quality of otherwise well-designed research studies (Shadish, Cook, & Campbell, 2002). Mindfulness research within and outside of social work has been rife with this prob- lem. An examination ofHick’s (2009)edited vol- umeMindfulness and Social Workclearly demonstrates this issue. According to Hick, mindfulness is“an orientation to our everyday experiences”( p. 1); to others in the edited volume, it is a“specific and effective method of focusing the mind on the ess- ence of experience”( p. 45), a way to“mediate the development of professional self-concept”( p. 93), “an approach for increasing awareness”( p. 125), an approach for“performing all activities with full awareness”( p. 154), and even a“necessary condi- tion for an activist to become mature in her passion and mission tofight for justice”( p. 178). This lack of conceptual clarity should be rectified and a uni- form, coherent set of definitions established, if mind- fulnessresearchwithinsocialworkistoadvance.

To that end, the following operationalizations of mindfulness are offered. First, mindfulness is astate, a naturalistic mindset characterized by an attentive and nonjudgmental metacognitive monitoring of moment-by-moment cognition, emotion, percep- tion, and sensation withoutfixation on thoughts of past and future (Garland, 2007;Lutz, Slagter, Dunne, & Davidson, 2008). Mindfulness is meta- cognitive in the sense that it involves a meta-level of awareness that monitors the content of con- sciousness while reflecting back upon the process of consciousness itself (Nelson, Stuart, Howard, & Crowley, 1999). Mindfulness is naturalistic in that it is a basic and inherent capacity of the human mind, although people differ in their ability and willingness to actualize this state (Brown, Ryan, & Creswell, 2007;Goldstein, 2002).

Second, mindfulness is apractice(or, more accu- rately, a set of practices) designed to evoke and fos- ter the state of mindfulness. The practice of mindfulness involves repeated placement of atten- tion onto an object while alternately acknowledg- ing and letting go of distracting thoughts and emotions. Objects of mindfulness practice can include the sensation of breathing; the sensation ofwalking; interoceptive (Craig, 2003) and proprio- ceptive (Brodal, 2004) feedback about the body’s internal state, movement, and position; visual stim- uli such as a candleflame or running water; mental contents such as thoughts or feelings; or the quality of awareness itself (Lutz et al., 2008). These prac- tices are taught and trained in mindfulness-based interventions.

Third, mindfulness is atraitor disposition that may be developed over time through the repeated practice of engaging in the state of mindfulness.

This trait may be characterized as the propensity toward exhibiting nonjudgmental, nonreactive awareness of one’s thoughts, emotions, experi- ences, and actions in everyday life (Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006). As a trait, mindfulness is roughly normally distributed (Walach, Buchheld, Buttenmüllerc, Kleinknechtc, & Schmidta, 2006). People vary in the extent to which they exhibit mindful dispositions, yet this dispositional- ity can be strengthened through training. People who participate in mindfulness-based interventions evidence increases in trait mindfulness, which med- iates the effects of training on clinical outcomes (Carmody & Baer, 2008).

Thus, integral to mindfulness is the notion of state by trait interaction, that is, recurrent activation of the mindful state via mindfulness practices leaves lasting traces that may accrue into durable changes in trait mindfulness (Garland, Fredrickson, et al., 2010), possibly mediated through neuroplasticity and experience-dependent alterations in gene expression (Garland & Howard, 2009). Indeed, recent research suggests that mindfulness practice can lead to increases in grey matter density in parts of the brain that subserve emotion regulation, learning, memory, and the ability to shift one’s perspective (Holzel et al., 2011). More research is needed to determine whether such neurobiologi- cal changes index the development of trait mind- fulness over time resulting from mindfulness training. USE RANDOMIZED CONTROLLED DESIGNS WHEREVER POSSIBLE A large number of social work studies use nonex- perimental and quasi-experimental research designs that are subject to severe threats to internal validity (Shadish et al., 2002). Despite the presence of these threats, authors often overstep the data by making causal claims from what are, at best, descriptive or 440 Social Work ResearchVolume 37, Number 4 December 2013 correlationalfindings. Studies that attempt to test causal hypotheses ( for example, hypotheses of therapeutic efficacy) using suboptimal research designs weaken the portfolio of social work research and lower the esteem of the profession in interdisciplinary venues.

This is an especially serious problem when it comes to research on mindfulness, which is still met with skepticism within many academic circles as a“New Age”or“mystical”practice that amounts to little more than a placebo. Hence, it is essential to use research designs in mindfulness research that can control for the effects of matura- tion, social desirability, expectancy, and placebo effects.

From 1990 through the early 2000s, many stud- ies on mindfulness used randomized wait-list con- trol groups ( for example,Astin, 1997;Davidson et al., 2003;Shapiro, Schwartz, & Bonner, 1998; Speca, Carlson, Goodey, & Angen, 2000). This type of research design is capable of controlling for history and maturation threats to validity as well as creating statistically comparable groups at baseline, and thus it represents a significant advance over nonrandomized or quasi-experimental studies with comparison groups. Yet, wait-list controlled designs remain vulnerable to threats to validity stemming from expectancy and placebo effects, which can be substantial (Shapiro, 1981).

Given these concerns, for much of the past dec- ade, mindfulness researchers have used randomized controlled trial designs in which participants are randomly assigned to either a mindfulness-based intervention or a credible, therapeutically active control condition. Perceived intervention credibil- ity can be measured with self-report scales, such as Borkovec and Nau’s (1972)Attitudes Towards Treatment Questionnaire, and statistically con- trolled (if necessary) in analyses of covariance. Such scales contain items assessing the extent to which the research interventions are perceived to be logi- cal treatments for the targeted clinical condition and how confident participants are that they will reduce their symptoms. Ideally, participants would perceive control treatments to be equally credible to experimental mindfulness interventions ( for example,Garland, Gaylord, et al., 2010;Gaylord et al., 2011). Expectancy effects can also be mini- mized through careful advertising of the research.

For example, aflyer that contains the statement “We are conducting research on mindfulness-based treatments for cocaine addiction”is in- herentlyflawed, as it suggests the treatment of interest or preference and potentially introduces expectancy effects that may confound study re- sults. In contrast, research advertisements should conceal the identity of the experimental and control treatments. For instance, the sameflyer would minimize expectancy effects by stating, “We are conducting research to compare the eff- ectiveness of two forms of treatment for cocaine addiction: a mindfulness-based treatment and a support group.” Moreover, the presence of significant main effects of time on clinical outcome variables sug- gests that the control condition may have been therapeutically active; yet, the presence of a signifi - cant Treatment × Time interaction term in the hypothesized direction indicates that the experi- mental mindfulness treatment led to significantly larger therapeutic change over time than the con- trol treatment. For example, in a randomized con- trolled trial of psychosocial treatments for irritable bowel syndrome,Gaylord et al. (2011)found that participants in a mindfulness training intervention and a conventional support group experienced sig- nificant reductions in abdominal pain; yet, relative to those in the support group, participants in the mindfulness training intervention experienced sig- nificantly greater reductions over the course of training.

The use of credible, therapeutically active con- trol groups may eliminate confounds introduced by expectancy and placebo effects as well as other nonspecific therapeutic factors such as atten- tion by a caring professional, group dynamics, soc- ial support, empathy, and the therapeutic alliance (Castonguay, Goldfried, Wiser, Raue, & Hayes, 1996;Duncan, Miller, & Sparks, 2007). When a study of a mindfulness-based intervention identi- fies significant clinical outcomes within the con- text of this rigorous research design, it may provide evidence against the“Dodo bird verdict”( for a re- view, seeBudd & Hughes, 2009). However, it should be noted that a study comparing a mindfulness-based intervention to a no-treatment control is asking a substantively different question than a study com- paring a mindfulness-based intervention to an active placebo control condition. In the former case, the design allows one to measure the efficacy of participation in a mindfulness-based interven- tion; whereas in the latter case, the design allows Garland /Mindfulness Research in Social Work 441 one to measure the efficacy of the active ingredient in a mindfulness-based intervention, that is, the practice of mindfulness itself. It should be noted that many active control conditions are not merely placebo controls, but instead are legitimate, estab- lished treatments. For example,Kuyken et al.

(2008)compared mindfulness-based cognitive therapy (MBCT) to maintenance of antidepressant medication as a means of preventing depression relapse. Thus, studies that use an active control group can ascertain whether mindfulness training is “more effective”than alternative treatments, in contrast to studies with a no-treatment control condition that answer the more basic question, “Is participation in a mindfulness-based interven- tion associated with positive clinical outcomes?” This is not to say that nonexperimental research designs have no place in mindfulness research. To the contrary, much can be learned about the associations between trait mindfulness and related constructs using cross-sectional or longitudinal research. However, it is imperative that authors draw careful conclusions that do not overstep the data. For instance, a prospective observational study of 339 individuals undergoing a mindfulness-based stress and pain management course found that participants reported significant improvements in trait mindfulness, positive reap- praisal coping, catastrophizing, and perceived stress over eight weeks of training (Garland, Gaylord, & Fredrickson, 2011). Further, the association between increases in trait mindfulness and decreases in stress was partially mediated by increases in posi- tive reappraisal but not by decreases in catastroph- izing. Although thesefindings are potentially clinically useful, one cannot conclude that mind- fulness training caused the observed changes. At best, one can only conclude that these changes occurred while participants were engaged in a mindfulness training program. Findings such as these are relevant only to the extent that they are interpreted with great precision; otherwise, they will remain unpublished or, worse, be pub- lished and tarnish the reputation of mindfulness researchers within and beyond academic social work.

Several key observational, quasi-experimental, and experimental research studies that represent the broad scope of research on mindfulness as a state, trait, and practice are presented in Table1. INVESTIGATE THERAPEUTIC MEDIATORS AND USE DISMANTLING DESIGNS Social work, as an appliedfield, is often myopically focused on clinical outcomes to the exclusion of more basic forms of scientific research. However, asking the question“By what processes does this treatment work?”is often a key step in refining and optimizing an intervention (Kazdin & Kendall, 1998;Kraemer, Wilson, Fairburn, & Agras, 2002).

For instance, if an initial study reveals that increases in trait nonreactivity mediate the therapeutic effect of mindfulness training on chronic pain (compare, Garland, Gaylord, Palsson, et al., 2012), mindful- ness interventions tested in future clinical research projects might emphasize techniques designed to increase nonreactivity in order to boost treatment effect sizes. Thus, examining therapeutic mediation could enable social work researchers to determine how mindfulness-based interventions might be targeted most effectively to the populations and to identify problems of greatest interest to clinical social workers in thefield. Therapeutic mediation can be tested by a number of statistical methods, in- cluding canonical regression procedure (Baron & Kenny, 1986), bootstrapping (Preacher & Hayes, 2004), structural equation modeling (Kline, 1998), or latent growth curve approaches (Preacher, Wichman, MacCallum, & Briggs, 2008), among others.

Moreover, by establishing the mediators of treat- ment, one can assess whether a treatment is inter- nally consistent with the theoretical orientation in which it is grounded (Hayes, Strosahl, & Wilson, 1999). This is important, both for maintaining the- oretical coherence and preventing reductionism and subsequent dismissal by researchers operating from other theoretical orientations. As one promi- nent example of this issue, mindfulness practices have been construed by some as relaxation tech- niques, believed to reduce stress via evocation of a relaxation response (Benson, Beary, & Carol, 1974). However, mindfulness meditation has been shown to produce significantly different cardiovas- cular and autonomic effects than relaxation training (Ditto, Eclache, & Goldman, 2006),findings that argue against the reductionistic construal of mind- fulness practice as a mere relaxation technique. Fur- ther, a randomized controlled trial demonstrated that whereas both mindfulness practice and relaxation training led to reduced distress, mindfulness practice alone led to significant decreases in ruminative 442 Social Work ResearchVolume 37, Number 4 December 2013 Table 1: Select Key Studies Representing the Broad Scope of Research on Mindfulness as a State, Trait, and Practice Study Sample DesignOperationalization of Mindfulness or Related Phenomena Pertinent Results Bowen et al.

(2012). Garland /Mindfulness Research in Social Work 443 thoughts that partially mediated its therapeutic effect on distress (Jain et al., 2007). Such results suggest that mindfulness practice exerts therapeutic effects by modifying cognitive processes, afinding that accords with extant theory on mindfulness.

It is also crucial to prevent the obscurations of eclecticism that can confound attempts to establish the efficacy of specific intervention techniques.

Although treatments that have received robust empirical support, such as cognitive behavior ther- apy (CBT), use multiple modes of intervention ( for example, CBT includes cognitive restructur- ing, behavioral activation, exposure, behavioral experiments, and other techniques), research on multimodal treatment packages remains subject to criticism. For instance,Longmore and Worrell (2007)review evidence that the addition of cogni- tive restructuring to behavioral activation tech- niques does not significantly increase treatment effects, suggesting that the cognitive component of CBT is neither necessary nor sufficient for thera- peutic change. The most commonly researched form of mindfulness training, mindfulness-based stress reduction (MBSR) (Kabat-Zinn, 1990), is also a multimodal treatment, which uses both mindfulness techniques and hatha yoga postures.

Although the efficacy of MBSR has been estab- lished in a number of trials (Chiesa & Serretti, 2009), it remains to be seen whether the therapeu- tic effects of the program derive more from its mindfulness or yoga components. To that end, dis- mantling studies are needed that partial out the differential effects of mindfulness treatment com- ponents by randomly assigning participants to receive one or more aspects of the multimodal intervention package (Shadish et al., 2002). How- ever, it is important to note that multimodal treat- ments are designed to promote synergistic effects by using different techniques that when combined produce more powerful clinical outcomes than the individual approaches alone ( for an example of a recent multimodal mindfulness intervention, see Garland, 2013). As such, dismantling studies are needed to complement, rather than supplant, research on multimodal mindfulness-based interventions.

USE BEHAVIORAL AND PHYSIOLOGICAL MEASURES OF MINDFULNESS AND THERAPEUTIC CHANGE As interest in mindfulness grows, there is a need to further specify and operationalize the measurementof mindfulness and its therapeutic effects in both clinical and basic science research programs. A number of questionnaires currently are used to quantify both state and trait mindfulness in studies, such as the Five-Facet Mindfulness Questionnaire (Baer et al., 2006) and the Toronto Mindfulness Scale (Lau et al., 2006). Although these scales can be useful, measurement instruments that rely on self-report are vulnerable to reactivity to being in an experimental condition, experimenter expec- tancies, social desirability biases, and misinterpreta- tion of question items (Shadish et al., 2002).

Moreover, it should be recognized that question- naire items are proxies for latent variables that can only imperfectly capture the essence of the con- struct under investigation (DeVellis, 2003). Any one operationalization may inadequately represent the construct of interest (Shadish et al., 2002).

As such, research on mindfulness as a state, trait, or practice that solely relies upon self-report instru- ments is subject to the same social influences and mono-operation biases as research on other psy- chosocial phenomena.

To counter the limitations of self-report mea- sures, mindfulness researchers may benefitfrom using behavioral and physiological measures of mindfulness and its therapeutic effects. In the past decade, there has been an explosion of studies in the psychological, medical, and neuroscientific lit- erature investigating the therapeutic mechanisms of mindfulness using an array of sophisticated research methodologies, including cognitive tasks ( for ex- ample,Garland, Boettiger, Gaylord, West Chanon, & Howard, 2012;Zeidan, Johnson, Diamond, David, & Goolkasian, 2011), psychophysiological measures ( for example,Garland, 2011;Ditto et al., 2006), and neuroimaging techniques ( for example, Farb et al., 2010;Froeliger, Garland, Modlin, & McClernon, 2012). Yet, in spite of the application of ever-increasing methodological rigor to research on mindfulness in thesefields, few social work scholars have dared to tread into this domain.

Whereas the implementation of many of biobeha- vioral methods (such as functional magnetic reso- nance imaging or DNA microarrays) requires years of specialized training not offered in most social work doctoral programs, other methods, such as the measurement of heart-rate variability, cortisol assays, and certain performance-based tasks derived from cognitive neuroscience, may be within reach of a wider range of social work researchers.

444 Social Work ResearchVolume 37, Number 4 December 2013 The use of such measures not only helps probe into questions of mechanism, but also provides a means with which to triangulate self-reports of change. For instance,Garland, Gaylord, et al. (2010) conducted a randomized controlled pilot trial com- paring the efficacy of a novel mindfulness-oriented cognitive intervention, mindfulness-oriented recovery enhancement (MORE), to that of an addiction support group for persons in long-term recovery from alcohol dependence. Results indicated that, relative to the support group, MORE led to signif- icant reductions in self-reported stress and thought suppression, but no changes in craving were obser- ved. This nullfinding might have suggested that this mindfulness-based intervention, although gen- erally therapeutically active, did not lead to changes addiction-specificfactors.Yet,manyclientsinre- covery are resistant to the term“craving”and are ret- icent to endorse experiencing it, particularly those in long-term residential treatment where the pressure to conform to social, cultural, and programmatic mores is high. Fortunately, non-self-report measures of alcohol cue-reactivity were assessed, including a dot probe task and a psychophysiological protocol, which determined the degree to which participants’ attention wasfixated on alcohol cues and the extent of heart-rate variability recovery from alcohol cue- exposure, respectively. MORE was found to modify both of these attentional and autonomic mechanisms implicated in alcohol dependence, suggesting that mindfulness training does in fact exert addiction- specific therapeutic effects. Moreover, individual difference analyses of change scores revealed that among participants in the mindfulness intervention, reductions in self-reported thought suppression were correlated with decreases in attentionalfixation on alcohol cues and increases in heart rate variability recovery from such cues. Thus, in a biopsychosocial research methodology, data from self-report mea- sures, cognitive tasks, and psychophysiological meth- ods converged in a theoretically sensible and mutually informative manner.

Psychophysiological research notwithstanding, investigators in afield as applied as social work should take pains to carefully document the spe- cific, behavioral outcomes of mindfulness as state, trait, and practice. For instance, variables such as frequency and duration of hospitalizations, number of arrests, and latency to re-incarceration are clearly quantifiable, clinically important, and reflective of real-world intervention impacts. Researchers couldassess whether changes in more proximal psycho- logical variables mediate the effect of mindfulness practice on these distal clinical outcomes. USE A MIXED-METHODS APPROACH Although researchers are increasingly using more rigorous methodologies to investigate mindfulness, little is known about how individuals utilize mind- fulness states, traits, and practices in their everyday lives to cope with stressors and emotional chal- lenges. Furthermore, the phenomenology of the change process as persons undergo mindfulness training remains unspecified. Although these areas of inquiry are to some extent tractable to quantita- tive research methods, they may also be fruitfully addressed through qualitative means.

Insofar as mindfulness is afirst-person phenome- non, that is, one that is directly accessible only to the person who is experiencing it (Depraz, Varela, & Vermersch, 2003),first-person accounts are nec- essary to capture the essence of the experience of mindfulness as it is perceived by those participating in mindfulness-based interventions. Grounded the- ory analyses of qualitative data derived from these reports may be used to triangulateetictheoretical conceptualizations of mechanisms by which mind- fulness facilitates coping ( for example,Garland, Schwarz, Kelly, Whitt, & Howard, 2012).

Data derived from in-depth interviews may be integrated with data from psychometric instru- ments, psychophysiological assessments, and so on.

Such a mixed-methods approach would capture the interpenetrating qualitative and quantitative aspects of mindfulness. One might, for example, complementfindings of mindfulness-induced changes in physiological stress reactivity with a “thick description”(Padgett, 1998) of how indi- viduals exhibiting such changes have learned to cope differently with distressing thoughts and emotions after mindfulness training. To that end, techniques such as protocol analysis (Ericsson & Simon, 1993) can be useful to precisely elucidate the mental steps and procedures taken by partici- pants of mindfulness-based interventions as they apply mindfulness skills to coping with adversity.

REMAIN MINDFUL OF CULTURAL AND CONTEXTUAL CONSIDERATIONS The Buddhist tradition from which mindfulness has been abstracted is grounded in a sort of ecological sys- tems theory, known aspratityasamutpada, sometimes Garland /Mindfulness Research in Social Work 445 translated as interdependent co-arising or what the venerable meditation teacher Thich Nhat Hanh simply called“interbeing”(Hanh, 1988).Pratitya- samputpadais the notion that all things are interre- lated and depend on one another for their existence. According to this notion, any being or entity is in fact the summation of an infinite number of causal forces extending from the past through the present and into the future. For example, the life of a human being in any given moment is influenced by the state of the world in that moment, in turn com- posed of environmental conditions, global and national political structures, cultural traditions, eco- nomic forces, community events, and social relation- ships. However, in a reciprocal fashion, the state of the world is conditioned by each human life; indeed, our every action changes the shape and contour of the world, in both a literal andfigurative sense.

In light of these considerations, social work researchers should remain mindful of the cultural and contextual forces that influence the implemen- tation and acceptability of mindfulness-based inter- ventions and the state of mindfulness itself. Clinical interventions are not delivered in a vacuum; they are delivered in a social, cultural, economic, and political context. It is notable that the overwhelm- ing majority of studies on mindfulness have been conducted with samples of white, middle- to upper- class individuals. For example, of the eight studies presented in Table1, only the studies conducted by Bowen et al. (2009)andGarland, Gaylord, et al.

(2010)included a racially and socioeconomically diverse sample. Mindfulness may indeed have a dif- ferent meaning for vulnerable persons facing pov- erty, homelessness, violence, and trauma who do not have the benefit of advanced education, eco- nomic resources, or political capital. Social work researchers are uniquely poised to assess interaction effects between client characteristics, sociocultural context, mindfulness training, and clinical outcomes.

Moderation analyses (Baron & Kenny, 1986)could be used to determine the effects of mindfulness train- ing on persons from different social strata and ethnic backgrounds. Such population-specific data should be integrated into a feedback loop that informs implementation of mindfulness-based interventions in thefield. In addition, principles endorsed in treat- ment manuals of mindfulness-based interventions (for example,Garland, 2013) should be couched in widely accessible vocabulary instead of sectarian and academic jargon. These practices will lead to theoptimization of mindfulness-based interventions for the focal populations and problems of interest to the social work profession. CONCLUSION The past decade has witnessed a proliferation of research on mindfulness, both within and beyond social work. Studies of mindfulness-based therapies may increasingly attract attention from the social work profession inasmuch as they illuminate the efficacy and cost-effectiveness of new forms of intervention. For example, a randomized control- led trial found that among persons in remission for major depression, MBCT was more effective in reducing residual depressive symptoms and improv- ing quality of life than antidepressant medication, yet was of comparablefinancial cost (Kuyken et al., 2008). Moreover, mindfulness-based inter- ventions may address emerging threats to public health and social welfare; in that regard, a recent early stage clinical trial identified significant thera- peutic effects of MORE on co-occurring prescrip- tion opioid misuse and chronic pain, a problem of increasing medical and sociological significance (Garland et al., 2013). In addition to itsfiscal and clinical efficacy, mindfulness is congruent with the strengths-based approach and empowerment ethos of social work. As a means of developing self- regulatory capacity, mindfulness practices enhance coping and thereby promote resiliency. Given the naturalfit between mindfulness and the overarching practice philosophy of the social work profession, there is a great need for social work researchers to thoughtfully engage in this important domain of inquiry.
