Behavioral control of exercise in adults: Studies 7 and 8

Abstract

Building on our previous six study series, the current studies 7 and 8 evaluated behavioral methods of improving adherence to exercise in adults. The studies tested the effectiveness of a single exercise modality versus choice of a variety of exercises and were conducted as part of a 12-week extended studies college course in San Diego, CA. Recruitment efforts were targeted to individuals who reported that they were sedentary and/or had experienced difficulty adhering to regular exercise. Participants were 42 adults (32F, 10M; mean age = 42.0) in Study 7 and 48 adults (35F, 8M; mean age = 47.9) in Study 8. In each study, subjects were randomly assigned to a single focus or variety exercise condition. There were no significant group differences in class attendance or out-of-class exercise adherence rates in Studies 7 or 8. In Study 7, significantly lower drop-out rates were detected in the single focus group (19%) than the variety condition (47.6%) (p = 0.04). No significant group differences were detected for drop-out rates in Study 8. Suggestions for further research are offered.     

Executive functions predict conceptual learning of science

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.     

Is It Worth Lying For? Physiological and Emotional Implications of Recalling Deceptive Affection

This investigation explored the risks of affectionate expressions in romantic relationships by examining the physiological and emotional implications of recalled expressed deceptive affectionate messages to romantic partners. Ninety‐nine participants were assigned to one of three conditions: deceptive affection, honest affection, or plans with a friend (control). Results indicate that individuals' blood pressure and heart rates are not differentially influenced when recalling deceptive affection compared to honest affection or common communication. Similarly, there were no differences in feelings of guilt and shame based on the motive for the deceptive expression. Posthoc analyses compared affectionate conditions (deceptive and honest) to the control condition and revealed no significant physiological differences. Implications for theory, methodological comparisons, and future research are discussed.     

Training Mental Health Professionals to Assess and Manage Suicidal Behavior: Can Provider Confidence and Practice Behaviors be Altered?

Remarkably little systematic research has studied the effects of clinical suicidology training on changing practitioner attitudes and behaviors. In the current study we investigated whether training in an empirically‐based assessment and treatment approach to suicidal patients administered through a continuing education workshop could meaningfully impact professional practices, clinic policy, clinician confidence, and beliefs posttraining and 6 months later. At the 6 month follow‐up we found that 44% of practitioners reported increased confidence in assessing suicide risk, 54% reported increased confidence in managing suicidal patients, 83% reported changing suicide care practices, and 66% reported changing clinic policy. These results suggest that a brief and carefully developed workshop training experience can potentially change provider perceptions and behaviors with a possible impact on clinical care therein.     

The Distillation of “VISCI”: Towards a Better Identification of Suicidal Inmates

The “Viennese Instrument for Suicidality in Correctional Institutions” (VISCI) presented here is based on the results of a large case‐control study and on research on literature examining suicide prevention in general and in the prison population in particular. The aim of this study was to validate the properties of the VISCI to differentiate between suicides and nonsuicides. The sensitivity and specificity of the VISCI was tested in the files of 55 correctional suicides, and 110 controls. VISCI differentiated well between suicides and nonsuicides. The routine administration of the VISCI may help to direct the existing professional attention to inmates with the highest need.     

Self‐Esteem and Suicide Ideation in Psychiatric Outpatients

Depression, hopelessness, and low self‐esteem are implicated as vulnerability factors for suicide ideation. The association of self‐esteem with suicide ideation after controlling for depressed mood and hopelessness was examined. Adult psychiatric outpatients (N = 338) completed measures of self‐esteem, suicide ideation, hopelessness, and depression. Self‐esteem was operationalized as beliefs about oneself (self‐based self‐esteem) and beliefs about how other people regard oneself (other‐based self‐esteem). Each dimension of self‐esteem was negatively associated with suicide ideation after controlling for depression and hopelessness. Of the two dimensions of self‐esteem, other‐based self‐esteem was the more robust predictor of suicide ideation. These findings suggest that even in the context of depression and hopelessness, low self‐esteem may add to the risk for suicide ideation.     

Impact of Death by Suicide of Patients on Thai Psychiatrists

The objective of this study was to identify the impact of a patient's suicide on psychiatrists in Thailand. A confidential coded postal questionnaire survey was sent to 320 eligible psychiatrists; with a response rate of 52.18%). The results showed that 94 (56.28%) of responding psychiatrists had a patient die by suicide, consistent with high rates found in similar large‐scale studies in the United States and United Kingdom. Less than half (41.5%) of patients had been diagnosed with schizophrenia, 33% had a depressive disorder, and the others had a wide array of diagnoses. More than 50% of psychiatrists reported personally experiencing sadness, depression, hopelessness, and guilt; 74.5% reported professional reactions, most frequently a review of their practice (93.4% reported being more aggressive in assessment of suicidality). Respondents were diverse in their postvention; 90% of Thai psychiatrists reported that working through with colleagues was most helpful. Family and friends helped. A majority (72.4%) of psychiatrists prayed or did “merit” for the dead patient; 86.8% found it helpful. This finding suggests that cultural sensitivity may be needed to understand the impact of suicide on psychiatrists but also to its response.
