Distress tolerance as a predictor of early treatment dropout in a residential substance abuse treatment facility

A large percentage of individuals who enter residential substance abuse treatment drop out before completing treatment. Given that early treatment dropout places individuals at an increased risk for relapse, identifying the mechanisms underlying treatment dropout would have several important theoretical and clinical implications. In the current study, the authors examined levels of psychological and physical distress tolerance as a predictor of early treatment dropout in a residential substance abuse treatment facility. In a sample of 122 individuals entering a residential substance abuse treatment facility, level of psychological distress tolerance was predictive of early treatment dropout above and beyond relevant self-report variables. There was no relationship between physical distress tolerance and early treatment dropout. Implications for future studies and treatment development or modification are discussed.     

MORPHINE TOLERANCE AS A FUNCTION OF RATIO SCHEDULE: RESPONSE REQUIREMENT OR UNIT PRICE?

Key pecking by 3 pigeons was maintained by a multiple fixed-ratio 10, fixed-ratio 30, fixed-ratio 90 schedule of food presentation. Components differed with respect to amount of reinforcement, such that the unit price was 10 responses per 1-s access to food. Acute administration of morphine, l-methadone, and cocaine dose-dependently decreased overall response rates in each of the components. When a rate decreasing dose of morphine was administered daily, tolerance, as measured by an increase in the dose that reduced response rates to 50% of control (i.e., the ED50 value), developed in each of the components; however, the degree of tolerance was smallest in the fixed-ratio 90 component (i.e., the ED50 value increased the least). When the l-methadone dose-effect curve was redetermined during the chronic morphine phase, the degree of cross-tolerance conferred to l-methadone was similar across components, suggesting that behavioral variables may not influence the degree of cross-tolerance between opioids. During the chronic phase, the cocaine dose-effect curve shifted to the right for 2 pigeons and to the left for 1 pigeon, which is consistent with predictions based on the lack of pharmacological similarity between morphine and cocaine. When the morphine, l-methadone, and cocaine dose-effect curves were redetermined after chronic morphine administration ended, the morphine and l-methadone ED50s replicated those obtained prior to chronic morphine administration. The morphine data suggest that the fixed-ratio value (i.e., the absolute output) determines the degree of tolerance and not the unit price.     

The role of distress tolerance in the relationship between depressive symptoms and problematic alcohol use

Empirical evidence and theory implicate the role of distress tolerance in the relationship between negative affect and alcohol use. However, limited research has been conducted to explore these relationships. As such, the purpose of this study was to examine whether distress tolerance moderates the relationship between current depressive symptoms and problematic alcohol use in a community sample of adults. Participants included 150 adults, primarily female, recruited from the local community. Problematic alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT) total score, which is a composite measure of harmful and hazardous patterns of alcohol use and several current alcohol dependence symptoms. Distress tolerance was measured using a computerized behavioral distress tolerance task, the Computerized Paced Auditory Serial Addition Task (PASAT-C). Tobit regression analyses indicated a significant interaction between distress tolerance and depressive symptoms in predicting alcohol problems, such that depressive symptoms were significantly associated with problematic alcohol use among adults with low, but not high, distress tolerance. Thus, alcohol use interventions with a focus on distress tolerance skills in the context of depressive symptoms may be particularly effective.

The deviant citizen: Measuring potential positive relations between counterproductive work behaviour and organizational citizenship behaviour

Studies have shown a strong negative correlation between counterproductive work behaviour (CWB) and organizational citizenship behaviour (OCB), and opposite correlations with hypothesized antecedents. Such observed correlations may have been erroneously caused by three measurement artefacts: items measuring absence of CWBs, rather than behaviours that exceed requirements or expectations in OCB scales; supervisory halo; and agreement rather than frequency response format. A new OCB scale, the OCB‐checklist (OCB‐C) was used that did not have these artefacts. Contrary to prior expectations from the literature, positive relations were found between CWB and OCB, and stressors and OCB. Theoretical explanations for positive CWB/OCB relations (demand‐elicited OCB, social loafing, work process problems, rater perceptions and attributions, and aggravated job stress processes) are discussed.     

Defining the Role of Laboratory Genetic Counselor

An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling.     

Using Small-Group Instruction to Improve Students' Reading Fluency: An Evaluation of the Existing Research

Reading fluency is necessary for reading comprehension, but approximately 40% of U.S. fourth-grade students have inadequate reading fluency skills. Because small-group (SG) instruction is often used as a first line of intervention for struggling readers, SG instruction targeting deficiencies in text reading fluency ought to be part of every school's intervention toolbox. The authors summarize the existing research on instruction and interventions that specifically targets reading fluency and is implemented by an adult with 3 or more students at once. Key findings revealed that most studies used a single-case design, nearly all studies were rated positively in terms of methodological quality, and the majority of participants significantly improved as a result of receiving SG intervention. Furthermore, of the five studies examining comparable SG and 1-on-1 interventions, 79% of the students performed equally well from both interventions. Implications and several recommendations for future research are discussed.     

The effects of exposure to feminist ideology on women's body image

Body image disturbance has become a common problem among women and there is a need to focus on creating empirically supported treatments. Psychoeducational interventions have reduced body image dissatisfaction, but their impact is limited because they do not offer women adaptive methods of interpreting the many appearance-related messages they receive. This study examined if exposure to a feminist perspective may provide alternative interpretations of cultural messages, thereby increasing body image satisfaction. Participants were randomly assigned to a feminist or psychoeducational intervention, or a control group. Exposure to the feminist condition resulted in increased self-identification as a feminist and greater appearance satisfaction, and changes in feminist identity were related to positive changes in body image. The findings indicate that exposure to feminist theories may serve as an effective intervention strategy.     

Self-stereotyping in the context of multiple social identities

This research examines self-stereotyping in the context of multiple social identities and shows that self-stereotyping is a function of stereotyped expectancies held in particular relationships. Participants reported how others evaluated their math and verbal ability and how they viewed their own ability when their gender or ethnicity was salient. Asian American women (Experiment 1) and European Americans (Experiment 2) exhibited knowledge of stereotyped social expectancies and corresponding self-stereotyping associated with their more salient identity. African Americans (Experiment 3) exhibited some knowledge of stereotyped social expectancies but no corresponding self-stereotyping. Correlational evidence and a 4th experiment suggest that self-stereotyping is mediated by the degree to which close others are perceived to endorse stereotypes as applicable to the self.
