A randomized trial of ACT bibliotherapy on the mental health of K-12 teachers and staff

The mental health challenges of some vocations present a challenge for current intervention models. Bibliotherapy focused on transdiagnostic processes that might both prevent and alleviate a range of mental health distress could be an effective and practical approach. K-12 school personnel (N = 236; 91% female; 30-60 years old) responding to a wellness-oriented program announcement were randomized to receive an Acceptance and Commitment Therapy (ACT) self-help volume or to a waitlist. Three-fourths were above clinical cutoffs in general mental health, depression, anxiety, or stress. Participants read the book for two months, completed exercises and quizzes, and after post assessment were followed for 10 weeks; waitlist participants were then also given the book with two months to complete it. Overall, participants showed significant improvement in psychological health. Significant preventive effects for depression and anxiety were observed along with significant ameliorative effects for those in the clinical ranges of depression, anxiety and stress. Follow up general mental health, depression, and anxiety outcomes were related to the manner in which participants used the workbook and to post levels of psychological flexibility.     

Previous mental health service utilization and change in clients' depressive symptoms

Although a potentially important factor in case conceptualization and treatment planning, the impact of previous treatment on subsequent counseling response has received little empirical attention. Using archival data, this study aimed to (a) report the prevalence of previous treatment utilization in a counseling population, (b) examine potential differences in symptom severity by treatment history, and (c) test whether the rate of change in symptoms over a course of counseling is moderated by previous treatment utilization, when also accounting for initial severity. A sample of 1,262 college students presenting for treatment in university/college counseling centers across the United States provided information on previous treatment history and completed the Counseling Center Assessment of Psychological Symptoms, administered at intake and up to 4 additional time points, with an average of 3-5 weeks between assessments. Data from the 13-item Depression subscale were used for the present study. Half the clients reported previous counseling, one third psychotropic medication, and one tenth psychiatric hospitalization. Previous treatment was associated with increased baseline depressive symptom severity. Results from latent growth curve models showed that previous counseling and medication correlated with a slower rate of symptom response, and previous counseling reduced the probability of being labeled a treatment responder. Previous counseling remained a significant predictor of counseling response when controlling for baseline severity. Hypothesized mechanisms through which previous treatment experience impacts subsequent treatment response remain largely theoretical and should be the focus of future research.     

ASSESSING AND INCREASING PHYSICAL ACTIVITY

Increasing physical activity is a crucial component of any comprehensive approach to combat the growing obesity epidemic. This review summarizes recent behavioral research on the measurement of physical activity and interventions aimed at increasing physical activity and provides directions for future research.     

Imageability estimates for 3,000 disyllabic words

We provide imageability estimates for 3,000 disyllabic words (as supplementary materials that may be downloaded with the article from www.springerlink.com ). Imageability is a widely studied lexical variable believed to influence semantic and memory processes (see, e.g., Paivio, 1971). In addition, imageability influences basic word recognition processes (Plaut, McClelland, Seidenberg, & Patterson, 1996). In fact, neuroimaging studies have suggested that reading high- and low-imageable words elicits distinct neural activation patterns for the two types e.g., Bedny & Thompson-Schill (Brain and Language 98:127-139, 2006; Graves, Binder, Desai, Conant, & Seidenberg NeuroImage 53:638-646, 2010). Despite the usefulness of this variable, imageability estimates have not been available for large sets of words. Furthermore, recent megastudies of word processing e.g., Balota et al. (Behavior Research Methods 39:445-459, 2007) have expanded the number of words that interested researchers can select according to other lexical characteristics (e.g., average naming latencies, lexical decision times, etc.). However, the dearth of imageability estimates (as well as those of other lexical characteristics) limits the items that researchers can include in their experiments. Thus, these imageability estimates for disyllabic words expand the number of words available for investigations of word processing, which should be useful for researchers interested in the influences of imageability both as an input and as an outcome variable.     

Brief Acceptance and Commitment Therapy and Exposure for Panic Disorder: A Pilot Study

Cognitive and biobehavioral coping skills are central to psychosocial therapies and are taught to facilitate and improve exposure therapy. While traditional coping skills are aimed at controlling maladaptive thoughts or dysregulations in physiology, newer approaches that explore acceptance, defusion, and values-based direction have been gaining interest. Acceptance and Commitment Therapy (ACT) involves creating an open, nonjudgmental stance toward whatever thoughts, feelings, and bodily sensations arise in a given moment, experiencing them for what they are, and moving toward them while inner experiences such as anxiety are present. This approach can be seen as consistent with exposure therapies and may be utilized to organize and facilitate engagement in exposure exercises. This study examines the feasibility and efficacy for combining a brief ACT protocol with traditional exposure therapy. Eleven patients with panic disorder with or without agoraphobia received 4 sessions of ACT followed by 6 sessions of exposure therapy, with data collected on a weekly basis. Acquisition of ACT skills and their application during exposure was monitored using a novel “think-aloud” technology. Treatment was associated with clinically significant improvements in panic symptom severity, willingness to allow inner experiences to occur, and reductions in avoidant behavior. Although preliminary, results suggest that our brief training in ACT only (as assessed prior to exposure exercises) and in combination with exposure therapy was acceptable to patients and offered benefits on the order of large effect sizes. Clinical and research implications are discussed.     

Acceptance and Commitment Therapy for Self-Stigma Around Sexual Orientation: A Multiple Baseline Evaluation

This study evaluated the effectiveness of 6 to 10 sessions of Acceptance and Commitment Therapy (ACT) for self-stigma around sexual orientation linked to same-sex attraction (what has generally been referred to as internalized homophobia; IH) in a concurrent multiple-baseline across-participants design. Three men and 2 women showed sizeable reductions from baseline to posttreatment and to 4- and 12-week follow-ups in daily reports of the degree to which thoughts about sexual orientation interfered in their lives; distress associated with these thoughts also decreased. Positive changes were observed in self-report measures of IH, depression, anxiety, stress, quality of life, and perceived social support. Consistent with the theory underlying ACT, reductions in daily ratings of the believability of thoughts about same-sex attraction (a process variable) were greater than those observed for frequency of such thoughts. Improvements were also observed in questionnaires measuring ACT processes. Mixed regression analyses confirmed outcome and process effects that were apparent through visual inspection. Implications and the distinctiveness of ACT as an approach are discussed.     

Infants' ability to categorise on the basis of rhyme

Two experiments are described, which investigated 7 - to 13-month-old infants' abilities to categorise syllables according to their ending sounds, or rhymes. Using the Conditioned Headturn (CHT) Procedure, infants were conditioned to turn their head when one set of rhyming CVCs changed to another set of rhyming CVCs. Even the 7 -month-old infants demonstrated an ability to categorise according to rimes. The infants could be separated into three different groups: those who conditioned but did not succeed in a rhyming task; those who succeeded at one rhyming task but not a second; and those infants who succeeded on two rhyming tasks. The infants in the second group were showing an early sensitivity to rhyme. However, they appeared to be learning a very specific rule, listening only for one category of rhyme. The third group of infants was able to extend the initial rule they learned to include new rhymes. This group learned not only to highlight one particular rhyme, but were also able to abstract the previously learned rule to new rhymes, thereby demonstrating a higher level of sophistication in their categorisation of rhymes. These results are discussed in relation to the ontogeny of language learning, and work demonstrating a relationship between rhyming ability and competence in reading and writing.
