A pilot study of cognitive-behavioral therapy of insomnia in people with mild depression

In some cases, insomnia and depression may have a reciprocal relationship, in which each aggravates and maintains the other. To test the hypothesis that reduction of insomnia would result in reduction of depression in patients (N=10) with both disorders, a repeated-measures design was used comparing depression and insomnia levels before and after 6 sessions of cognitive-behavioral therapy of insomnia. Posttreatment, 100% of completers (n=8) had a normalized sleeping pattern, and 87.5% had normalized depression scores. Significant posttreatment improvement was seen in sleep onset latency (-31 min), wake time after sleep onset (-24 min), total sleep time (+65 min), sleep efficiency (+14%), and sleep quality (+19%), which was maintained at 3-month follow-up. A decreasing trend occurred in depression scores from pre- to posttreatment, which reached significance at 3-month follow-up. Intent-to-treat analyses showed similar results.     

The relationships among asymmetry in task dependence, perceived helping behavior, and trust

Social relations analyses involving 132 working relationships among 60 individuals from 29 teams revealed that an increase in a team member's task dependence on another team member was associated with higher levels of perceived help from and interpersonal trust in that specific team member, provided the other member was highly task dependent on the focal member. The degree to which an actor perceived a relationship with a partner to be helpful partially mediated the relationship between task dependence and trust. These findings highlight the importance of attending to asymmetries in task dependence and provide valuable insights into mechanisms that can explain the development of trust in organizational work teams.     

The tripartite model for assessing symptoms of anxiety and depression: psychometrics of the Dutch version of the mood and anxiety symptoms questionnaire

AIM: The tripartite model conceptualizes symptoms of depression and anxiety in three groups: low positive affect and anhedonia, which is specific to depression, somatic arousal, which is unique to anxiety, and nonspecific general distress. The Mood and Anxiety Symptoms Questionnaire (MASQ) was developed to measure these symptom domains. This study reports on the psychometric properties of the Dutch translation of the MASQ. METHOD: The questionnaire was completed by a population-based sample and by patients with anxiety and/or mood disorders. Scores of these respondent groups were compared to assess the discriminant validity of the MASQ and evaluate the appropriateness of the tripartite model. RESULTS: The psychometric properties of the translated MASQ were highly satisfactory. In accordance with the model, we found the MASQ to comprise three main scales, which discriminate well between subgroups of patients with mood and anxiety disorders. DISCUSSION: Overall, like the English version the Dutch translation of the instrument appears to be a reliable and valid measure of symptoms of depression and anxiety, conceptualized as comprising three groups of symptoms. The Dutch MASQ is better able to distinguish unique aspects of mood and anxiety disorders than other self-report instruments.     

Cognitive-behavioral therapy for women with lifelong vaginismus: process and prognostic factors

Cognitive-behavioral therapy (CBT) seems an effective treatment of lifelong vaginismus, but mechanisms of action have not yet been established. The present study explored whether the effect of CBT for lifelong vaginismus is mediated by changes in fear of penetration and avoidance behavior, which CBT explicitly aims to alter. A second aim of this study was to predict treatment outcome on the basis of pre-treatment variables. Participants with lifelong vaginismus were allocated at random to a 3-months CBT (n=81) or a waiting-list control condition (n=36). Full vaginal penetration with the penis of the partner constituted the primary outcome measure. Change scores in successful 'non-coital penetrative-behavior' and 'fear of coitus' were used to measure the mediating variables. Treatment resulted in an increase of intercourse (outcome), a decrease in fear of coitus, and an enhancement of successful non-coital penetration behavior, compared with no treatment. Outcome (intercourse) was partly mediated by changes in fear of coitus and changes in avoidance behavior. No treatment predictors could be detected in this study sample. It is concluded that techniques such as gradual exposure, aimed at decreasing avoidance behavior and penetration fear, constitute an important avenue of change in the treatment of lifelong vaginismus.     

Effects of a School‐Based Life Skills and HIV‐Prevention Program for Adolescents in Mexican High Schools1

A school‐based life skills and sexuality education HIV/AIDS program for adolescents was evaluated in Toluca, Mexico, through a quasi‐experimental pre–post design with 1,566 cases, divided over a control group and an experimental group. Based on a previously tested path model, 3 levels of variables were included as a guide for the contents of the program: personal variables (self‐knowledge, self‐efficacy regarding condom use, and decision making), intervening variables (subjective norms about, knowledge about HIV/AIDS, and attitudes toward condoms), and outcome variables (communication on sexuality and intentions to use condoms). Evaluation was conducted following these categories. Significant increases in all of these variables recognized as precursors of safer sex were found in the experimental group.     

Positive and negative associations underlying ambivalent attitudes

In two studies, we compared the strength of positive and negative associations of ambivalent attitudes to those of nonambivalent attitudes. In Study 1, results from an implicit association task showed that, in contrast to nonambivalent attitudes, ambivalent attitudes were characterized by strong positive and negative associations. In Study 2 responses to ambivalent attitude objects were faster following a positive as well as following a negative prime, compared to a non-word prime, whereas for neutral attitude objects prime type did not influence response times. Results provide direct evidence for the assumption that both positive and negative associations of ambivalent attitudes are relatively strong. Implications for attitude strength and attitude structure are discussed.     

Individual differences in adult decision-making competence

The authors evaluated the reliability and validity of a set of 7 behavioral decision-making tasks, measuring different aspects of the decision-making process. The tasks were administered to individuals from diverse populations. Participants showed relatively consistent performance within and across the 7 tasks, which were then aggregated into an Adult Decision-Making Competence (A-DMC) index that showed good reliability. The validity of the 7 tasks and of overall A-DMC emerges in significant relationships with measures of socioeconomic status, cognitive ability, and decision-making styles. Participants who performed better on the A-DMC were less likely to report negative life events indicative of poor decision making, as measured by the Decision Outcomes Inventory. Significant predictive validity remains when controlling for demographic measures, measures of cognitive ability, and constructive decision-making styles. Thus, A-DMC appears to be a distinct construct relevant to adults' real-world decisions.     

The role of memory for compounds in cue competition

Revisions of common associative learning models incorporate a within-compound association mechanism in order to explain retrospective cue competition effects (e.g., [Dickinson, A., & Burke, J. (1996). Within-compound associations mediate the retrospective revaluation of causality judgements. Quarterly Journal of Experimental Psychology, 49B, pp. 60-80.]). These models predict a correlation between memory for compounds (as a measure for the strength of within-compound associations) and retrospective cue competition but not forward cue competition. This was indeed found in a study of [Melchers, K. G., Lachnit, H., & Shanks, D. (2004). Within-compound associations in retrospective revaluation and in direct learning: A challenge for comparator theory. Quarterly Journal of Experimental Psychology, 57B, pp. 25-54.]. We argue that a higher-order reasoning account of causal learning can also explain the evidence for the role of within-compound associations in cue competition. Moreover, this account predicts that if making inferences during the learning stage is impeded, a correlation between memory for compounds and forward cue competition should be found as well. The results of a new study confirmed this prediction.     

Psychometric evaluation of the Brazelton Scale in a sample of Spanish newborns

This study analyses the data obtained from a sample of 220 healthy full-term neonates evaluated with the Neonatal Behavioral Assessment Scale, NBAS, 3rd edition. Standard scores were obtained for each of the 35 behavioral items and analysis of the main components of all the clusters was performed. Similarly to the original scale, the five following factors were obtained: Autonomic and Motor Systems, Habituation, State Organization, State Regulation, and Social Interactive. The analysis of the reliability of these groupings reveals that it is between moderate and high (the average Cronbach's alpha coefficient was .78).
