Correlates of organizational commitment: Differences in the public and private sector

Private and public sector managers were compared regarding their job characteristics and organizational commitment. We hypothesized that job characteristics would be positively related to commitment and that sector would moderate that relationship. Moderated regression analyses revealed partial support for both hypotheses. The existence of clarity and challenge were positively related to commitment. Job characteristics demonstrated a stronger relationship with commitment among private sector managers. Explanations for these findings and directions for future research are discussed.     

Children's need for approval and achievement motivation: An interactional approach

This study examined the effects of children's need for approval (nApp) and a situational variable-frequency of expectancy statements-on children's achievement cognitions and behaviour. We replicated the Dweck and Gilliard (1975) paradigm, but also mea sured children's nApp. Ninety fifth grade boys and girls stated expectancies either prior to each trial, prior to the first and last trials, or prior to the last trial only. We found that although high and low nApp children lowered their expectancies after failure, high nApp children lowered them less than low nApp children. In contrast, persistence was influenced only by the frequency of expectancy statements and not by children's nApp. The results are discussed in the context of the interactional point of view in personality psychology.     

Route-finding: A measure of everyday executive functioning in the head-injured adult

This is an ecological test of adaptation in head-injured adults, reporting reliability and validity of the Executive Function Route-finding Task (EFRT; Boyd and Sautter, 1985). A Likert scale was used to rate executive aspects of route-finding such as task formulation, strategy of approach, detection and correction of errors, and dependence on cueing among 31 head-injured young adults within a large rehabilitation facility. The Task has high inter-rater reliability and acceptable concurrent validity with other neuropsychological constructs.     

A comparison of Guided Imaginal Coping and imaginal exposure in the treatment of panic disorder

The present study evaluated the efficacy of a new intervention, Guided Imaginal Coping (GIC), compared to imaginal exposure (IEX), and a waiting-list control (WLC) condition among 24 clinic outpatients meeting DSM-III-R criteria for panic disorder (PD) or PD with agoraphobia. GIC was the more consistently effective intervention, with individuals demonstrating significant improvement in frequency and severity of panic attacks (Pas) as well as significant reductions in physiological and subjective arousal to provocative imagery. Individuals in the IEX intervention demonstrated less consistent improvement on the dependent measures, while individuals in the WLC condition essentially remained unchanged. Both GIC and IEX were effective according to a composite measure of clinically significant improvement. However, only GIC was superior to the WLC condition when clinical improvement was defined as zero PAs at follow-up. These findings, while preliminary, suggest that GIC can be added to the armamentarium of effective approaches to treating PD.     

Self-Monitoring negative statements

We examined the effects of a self-monitoring program on reducing the frequency of negative statements of a student with mild mental retardation who was enrolled in a self-contained classroom at a middle school. A changing criterion design was used within a multiple baseline design across two classroom periods. Additionally, the frequency of positive statements was reported. The results showed a decrease in the number of negative statements, and an increase in the number of positive statements. Maintenance data collected up to 8 weeks after the program ended indicated that the student continued to emit positive rather than negative statements. The use of this procedure to decelerate undesirable behavior is discussed.     

Family preservation using multisystemic treatment: Long-term follow-up to a clinical trial with serious juvenile offenders

In a randomized clinical trial, multisystemic family preservation was shown to significantly reduce rates of criminal activity and incarceration in a sample of 84 serious juvenile offenders and their multi-need families. In the current study, archival records were searched for re-arrest an average of 2.4 years post-referral. Survival analysis showed that youths who received multisystemic family preservation were less likely to be re-arrested than were youths who had received usual services. Such results represent the first controlled demonstration that family preservation, when delivered via a clearly specified treatment model, has lasting effects with serious juvenile offenders. Implications for family preservation and juvenile justice research are discussed.     

Nonsuicidal physically self-damaging acts in adolescents

To determine the frequency and correlates of nonsuicidal physically self-damaging acts in 12–14 year olds, a two stage epidemiologic survey with a self-administered questionnaire (N=3283) followed by a psychiatric interview of a subsample of the adolescents and their parents (N=444) was used. Prevalence estimates of interview validated nonsuicidal physically self-damaging acts were 2.46% in males and 2.79% in females. Significant relationships were found between nonsuicidal physically self-damaging acts and suicidal ideation, major depression and undesirable life events. Data suggest that physically self-damaging acts occur at substantial rates during early adolescence. The strong correlation between nonsuicidal self-destructive acts and both suicidal ideation and major depression clarifies prior conflicting reports in the literature and suggests that a history of self-damaging acts should be taken into consideration when evaluating for possible depression and suicide risk.     

Perceptions of maternal and paternal solicitude by birth children and adoptees: Relevance for maternal bonding theory

This study emanated from the long-standing question of whether a maternal bonding process similar to other mammalian species occurs in humans. The perceptions of adult adoptees and a matched sample of non-adoptees about their parents' behaviours towards them were compared on an original Parental Solicitude Scale. As hypothesized, birth children perceived their mothers as the more solicitous parent, but ratings of adoptive mothers showed a unilateral decline. Further, the differential ratings for birth and adoptive mothers occurred mostly for the factors labelled benignity vs abuse and tolerance vs control, rather than caretaking vs neglect, which was congruent to reported effects in prior studies of lack of mother-infant contact during the sensitive period for bonding. An alternative explanation of the data was also tested but not substantiated.     

The role of spatial frequency in the processing of hierarchically organized stimuli

Can spatial frequency differences between local and global forms account for differences in the way different levels of structure are analyzed? We examined this question by having subjects identify local or global forms of hierarchical stimuli that had beencontrast balanced. Contrast balancing eliminates low spatial frequencies, so that both local and global forms must be identified on the basis of high spatial frequency information. Response times (RTs) to global (but not local) forms were slowed for contrast-balanced stimuli, suggesting that low spatial frequencies mediate the global RT advantage typically found. In contrast, interference between local and global forms was little affected by contrast balancing or by shifts of attention between local and global forms, suggesting that it does not result from inhibitory interactions between spatial frequency channels or from temporal precedence of low versus high spatial frequency information. Finally, shifts of attention between local and global forms were also little affected by contrast balancing, suggesting that they were not based on spatial frequency.
