The assessment of behavioural activation—the relationship between positive emotionality and the behavioural activation system

Much personality research suggests that the variance in personality can be accounted for by a few dimensions, often hypothesized to be connected to neurological circuits. Gray's ( 1982 ) behavioural activation system (BAS) and behavioural inhibition system (BIS) in particular propose to explain for a variety of behaviour. This investigation sought to determine whether Positive Emotionality is an appropriate measure of the BAS, and how Tellegen's ( 1985 ) constructs are related to BAS activity. Measures of BAS and Positive Emotionality were administered to undergraduates. Confirmatory factor analyses revealed that, while Positive Emotionality can be used as an indicator of BAS activity, it is better conceived of as a distinct, correlated construct. In addition, not all components of Positive Emotionality were related to BAS activity, and BAS was further related to components of Negative Emotionality and Constraint.

Factor Structure of the Beck Depression Inventory—II in a Medical Outpatient Sample

This study examined the factor structure of the Beck Depression Inventory—II (BDI-II) in a sample of 127 individuals referred by their primary care physicians. Using exploratory factor analysis with oblique rotation, a 2-factor model appeared to be the most parsimonious representation of the data. The rotated factors accounted for approximately 53% of the variance. Consistent with previous research, the first factor was interpreted as a somatic–affective dimension and the second factor reflected a cognitive dimension. The correlation between these 2 factors was .79. It appears possible to divide the BDI-II into subscales to facilitate interpretation in medical patients.     

Basic psychological needs satisfaction,working alliance,and early termination in psychotherapy

The goal of this study was to evaluate the relationship between basic psychological needs satisfaction and working alliance in psychotherapy and to determine whether client ratings of basic needs and working alliance during psychotherapy were associated with early termination of therapy. Former psychotherapy clients (n = 87) completed a semi-structured interview regarding basic needs satisfaction in therapy, working alliance and dropout status. Participant ratings on the Basic Needs Satisfaction in Psychotherapy scale (BNSP) and the Retrospective Working Alliance Inventory – Short (RWAI-S) were significantly correlated (r = .77) in our sample. A comparison of intercorrelations between working alliance subscales and basic needs subscales indicated higher factorial distinctiveness within the basic needs measure. T-tests comparing those who terminated psychotherapy early with those who had planned endings on scores on the BNSP and RWAI-S were significant (Cohen’s d = .65 and 1.82, respectively). Results suggest that the basic needs measure might tap into a wider breadth of the therapist and client interaction than the RWAI-S.     

Anxiety and outcome predictions

Research shows that people display a downward shift in their predictions in anticipation of performance and feedback. The authors used a misattribution paradigm to explore whether anxiety serves as a signal for predictions. Participants (N = 108) anticipating results from an important test either immediately or in a few days were or were not encouraged to attribute any arousal they experienced to coffee they consumed earlier. Consistent with predictions, participants encouraged to attribute their arousal to the coffee were optimistic in their predictions even when anticipating immediate test feedback. In addition, the more participants attributed their arousal to the coffee, the more optimistic they were in their predictions. Ancillary analyses suggest that anxiety can be a cause rather than a consequence of less optimistic predictions.     

Traumatic impact predicts long-term memory for documented child sexual abuse

Prospective studies of adults' memories of documented child sexual abuse (CSA) reveal that the majority of individuals remember their victimization. However, the accuracy of these memories has rarely been investigated scientifically. The present study examined predictors of memory accuracy and errors 12 to 21 years after abuse ended for individuals with legal experiences resulting from documented CSA. Severity of posttraumatic stress disorder (PTSD) symptomatology was positively associated with memory accuracy. However, individuals nominating CSA as their most traumatic life event exhibited relatively accurate memory regardless of indicators of PTSD. Predictors of memory errors were also identified (e.g., less maternal support). These results indicate that, in addition to understanding the role of traditional cognitive factors, understanding an event's traumatic impact is important for predicting the accuracy of long-term memory for reported CSA.     

What can subjective forgetting tell us about memory for childhood trauma?

In the present study, we examined the prevalence and predictors of subjective forgetting (i.e., self-reported amnesia) of child sexual abuse (CSA). Adults who, as children, were involved as victims in legal prosecutions were questioned about their CSA experiences, which had been documented in the 1980s, and about lost and recovered memory of those experiences. Males and individuals who experienced more severe abuse were more likely to report forgetting. The majority of individuals attributed their forgetting to active attempts to avoid thinking about the abuse. In contrast, when predictors of subjective forgetting were used to predict objective memory of abuse, more severe abuse and more extended legal involvement were associated with fewer memory errors. The differences between subjective and objective memory underscore the risks of using subjective measures to assess lost memory of abuse.     

Children's memories of experienced and nonexperienced events following repeated interviews

The present study compared 3- and 5-year-olds' reports of a true or false play interaction following repeated interviews. Final interviews were conducted either by the same researcher or by a new researcher. Age-related improvements in performance were evident. Also, 3-year-olds questioned repeatedly about an entirely false event made more errors in response to specific questions than 3-year-olds questioned repeatedly about false details of a true event. Five-year-olds who were questioned about the false event, however, were particularly accurate when answering questions about never-experienced body touch. Interviewer familiarity was associated with decreases in the amount of narrative detail 5-year-olds provided in free-recall and with increases in 3-year-olds' accuracy in response to direct questions. Both errors and response latency on a cognitive matching task were related to children's suggestibility.     

Stress and emotional valence effects on children's versus adolescents’ true and false memory

Despite considerable interest in understanding how stress influences memory accuracy and errors, particularly in children, methodological limitations have made it difficult to examine the effects of stress independent of the effects of the emotional valence of to-be-remembered information in developmental populations. In this study, we manipulated stress levels in 7–8- and 12–14-year-olds and then exposed them to negative, neutral, and positive word lists. Shortly afterward, we tested their recognition memory for the words and false memory for non-presented but related words. Adolescents in the high-stress condition were more accurate than those in the low-stress condition, while children's accuracy did not differ across stress conditions. Also, among adolescents, accuracy and errors were higher for the negative than positive words, while in children, word valence was unrelated to accuracy. Finally, increases in children's and adolescents’ cortisol responses, especially in the high-stress condition, were related to greater accuracy but not false memories and only for positive emotional words. Findings suggest that stress at encoding, as well as the emotional content of to-be-remembered information, may influence memory in different ways across development, highlighting the need for greater complexity in existing models of true and false memory formation.     

EXTINCTION OF SELF-INJURIOUS ESCAPE BEHAVIOR WITH AND WITHOUT INSTRUCTIONAL FADING

Three individuals with developmental disabilities participated in a study of the treatment of self-injurious behavior (SIB) maintained by negative reinforcement (escape from educational tasks). Treatment was implemented in a multiple baseline design across subjects, in which two treatments were compared in a multielement format. Both treatment conditions included an escape-extinction component in which SIB no longer produced escape. One of the conditions also included a fading component in which the frequency of instructions was initially reduced to zero and then was gradually faded back in across sessions until the instructional rate matched that of the original baseline. Results indicated that extinction alone reduced SIB to the end-of-treatment criterion in fewer sessions than did extinction plus fading for all 3 subjects. For 2 of the 3 subjects, however, there was an initial increase in the frequency of SIB at the outset of treatment with extinction (an extinction burst) that was not observed when extinction was combined with the fading component.
