Testing discrepancy effects: A critique, a suggestion, and an illustration

To assess the effects of discrepancy between two independent variables, investigators sometimes compute difference scores and correlate such scores with a criterion variable. However, the correlation of the difference with the criterion is accounted for by the correlations of the difference constituents with the criterion and the constituents’ variances. It follows that when investigators are testing a prediction that is not captured by the difference constituents’ main effects, using the difference correlation analysis may be misleading. Under these circumstances, the effects of a discrepancy between two independent variables can be assessed by a test of their interaction. The problems inherent in using difference scores and the advantage of testing the interaction are illustrated in relation to research programs on two separate topics in social psychology.     

Gendered Division of Childrearing: Ideals,Realities, and the Relationship to Parental Well-Being

Recent cultural expectations about fathers' involvement in childrearing may have changed more rapidly than fathers' behaviors, creating discrepancies between parenting ideals and realities that can generate tensions in family life. In this study, a 1999 national probability sample of 234 married parents, both mothers and fathers expressed strongly egalitarian ideals that fathers should be equally involved in child-rearing across five nurturant domains—discipline, emotional support, play, monitoring, and care-giving—as well as in financial support. In contrast, mothers perceived much less father involvement in actual parenting than fathers perceived—especially in disciplining and providing emotional support for their children. Ideal–actual discrepancies were related to well-being: if fathers were seen as less than ideally involved in nurturant parenting, parents reported more stress and fathers who perceived greater than ideal father involvement in financial support were more likely to say the division of household labor was unfair to the mother. Ideal–actual gaps differed for mothers and fathers and were sometimes differentially related to well-being. For example, less than ideal father involvement in disciplining children was associated with mothers' higher stress levels, and the discrepancy in expectations about father involvement in play and monitoring children was correlated with mothers' increased feelings of unfairness in the household division of labor. On the other hand, fathers who felt an ideal–actual gap in disciplining children almost always felt overly involved in discipline and were less likely to report that the division of labor in the household was unfair to their spouses.     

Neural Correlates of Reward Processing in Adolescents With a History of Inhibited Temperament

ABSTRACT— Functional imaging data were acquired during performance of a reward-contingency task in a unique cohort of adolescents (ages 14–18 years) who were characterized since infancy on measures of temperamental behavioral inhibition. Neural activation was examined in striatal structures (nucleus accumbens, putamen, caudate) with a known role in facilitating response to salient reward-related cues. Adolescents with a history of behavioral inhibition, relative to noninhibited adolescents, showed increased activation in the nucleus accumbens when they believed their selection of an action would affect reward outcome. Neural responses did not differ between the two groups when participants made a prespecified response that they knew would result in reward or when they produced random motor responses that they knew would not be rewarded. These results link inhibited temperament and perturbed neural responses to reward-contingency cues.     

Twenty-five Years of Research on Childhood Anxiety Disorders: Publication Trends Between 1982 and 2006 and a Selective Review of the Literature

We examined trends in publications on childhood anxiety disorders over the past 25 years. A PsycINFO search was carried out to find relevant research articles published between 1982 and 2006. Results indicated a gradual and significant rise in the frequency of publications on childhood anxiety disorders during the past 25 years, and this increase was particularly strong for post-traumatic stress disorder, obsessive–compulsive disorder, social phobia, and multiple anxiety disorders. Most studies concerned the phenomenology of childhood anxiety disorders (i.e., >50%). Considerable less research has been conducted on the etiology, intervention, and assessment of these disorders in youths. Nevertheless, the conclusion seems warranted that the research on childhood anxiety disorders has made significant advancements during the past decades. This notion is supported by a selective review of the literature, which highlights important developments in this field of study.     

Acetylcholine activity in selective striatal regions supports behavioral flexibility

Daily living often requires individuals to flexibly respond to new circumstances. There is considerable evidence that the striatum is part of a larger neural network that supports flexible adaptations. Cholinergic interneurons are situated to strongly influence striatal output patterns which may enable flexible adaptations. The present experiments investigated whether acetylcholine actions in different striatal regions support behavioral flexibility by measuring acetylcholine efflux during place reversal learning. Acetylcholine efflux selectively increased in the dorsomedial striatum, but not dorsolateral or ventromedial striatum during place reversal learning. In order to modulate the M2-class of autoreceptors, administration of oxotremorine sesquifumurate (100 nM) into the dorsomedial striatum, concomitantly impaired reversal learning and an increase in acetylcholine output. These effects were reversed by the m(2) muscarinic receptor antagonist, AF-DX-116 (20 nM). The effects of oxotremorine sesquifumurate and AF-DX-116 on acetylcholine efflux were selective to behaviorally-induced changes as neither treatment affected acetylcholine output in a resting condition. In contrast to reversal learning, acetylcholine efflux in the dorsomedial striatum did not change during place acquisition. The results reveal an essential role for cholinergic activity and define its locus of control to the dorsomedial striatum in cognitive flexibility.     

The Future is Bright? Effects of Mood on Perception of the Future

Most people believe that the future will bring them more good things than bad, and therefore have high hopes for the future (MacLeod et al. Cogn Emot 10:69–85, 1996). However, many patients with mood disorders do not hold this positive belief about the future. At the extreme, low expectations of positive outcomes in the future can lead to feelings of hopelessness (O’Connor et al. Psychol Health Med 5:155–161, 2000). This paper aims to extend the literature on subjective probability of future events, using a mood induction paradigm to examine the effects of transient mood change on perceived likelihood of future events in a non-clinical community sample. Participants rated likelihood of future events from a standardized list and from their own lives. Ratings were made in both normal and experimentally-induced positive or negative mood. Results show that self-generated future events were perceived to be more likely than those from a standardized list, and that negative mood significantly biased perceived likelihood of other-generated future events. Participants rating standardized list events saw positive outcomes as less likely and negative outcomes as more likely in induced negative mood than they did in normal mood. Mood had no effect on ratings of self-generated events. Possible directions for future research are discussed.

Life Satisfaction,Self‐Esteem,and Subjective Age in Women Across the Life Span

A study of 320 women, ages 21 to 69, explored the relations among relationship status, subjective age, self‐esteem, and life satisfaction. Women in married or partnered relationships had higher levels of life satisfaction than did single women. Women in their 30s and 40s had significantly lower levels of life satisfaction than did other age groups.     

Cognitive-behavioural therapy for adolescents with bulimic symptomatology: The acceptability and effectiveness of internet-based delivery

Background

The evidence base for the treatment of adolescents with bulimia nervosa (BN) is limited.

Aims

To assess the feasibility, acceptability, and clinical outcomes of a web-based cognitive-behavioural (CBT) intervention for adolescents with bulimic symptomatology.

Method

101 participants were recruited from eating disorders clinics or from beat, a UK-wide eating disorders charity. The programme consisted of online CBT sessions (‘Overcoming Bulimia Online’), peer support via message boards, and email support from a clinician. Participants' bulimic symptomatology and service utilisation were assessed by interview at baseline and at three and six months. Participants' views of the treatment package were also determined.

Results

There were significant improvements in eating disorder symptoms and service contacts from baseline to three months, which were maintained at six months. Participants' views of the intervention were positive.

Conclusions

The intervention has the potential for use as a first step in the treatment of adolescents with bulimic symptomatology.
