Examination of the MMPI-2 Restructured Clinical (RC) Scales in a Sample of Bariatric Surgery Candidates

The current study examined the MMPI-2 Restructured Clinical (RC) scales (Tellegen et al., MMPI-2 Restructured Clinical (RC) scales: Development, validation, and interpretation. Minneapolis: University of Minnesota Press, 2003) in a sample of 1,091 bariatric surgery candidates. The RC scales were developed to address concerns about limited discriminant validity of the Clinical scales. Internal consistency and external validity analyses were conducted to evaluate the RC scales in this setting. Results indicated that the RC scales are generally more internally consistent than the Clinical scales and display significantly better convergent and discriminant validity in predicting a variety of behavioral, psychological, and developmental variables relevant to preoperative bariatric psychological evaluations. Implications of the results and recommendations for future research with the RC scales in medical settings are discussed.     

Community vs. Clinic-Based Modular Treatment of Children with Early-Onset ODD or CD: A Clinical Trial with 3-Year Follow-Up

This study examines the treatment outcomes of 139, 6–11 year-old, clinically referred boys and girls diagnosed with Oppositional Defiant Disorder (ODD) or Conduct Disorder (CD) who were randomly assigned to a modular-based treatment protocol that was applied by research study clinicians either in the community (COMM) or a clinic office (CLINIC). To examine normative comparisons, a matched sample of 69 healthy control children was included. Multiple informants completed diagnostic interviews and self-reports at six assessment timepoints (pretreatment to 3-year follow-up) to evaluate changes in the child’s behavioral and emotional problems, psychopathic features, functional impairment, diagnostic status, and service involvement. Using HLM and logistic regression models, COMM and CLINIC showed significant and comparable improvements on all outcomes. By 3-year follow-up, 36% of COMM and 47% of CLINIC patients no longer met criteria for either ODD or CD, and 48% and 57% of the children in these two respective conditions had levels of parent-rated externalizing behavior problems in the normal range. We discuss the nature and implications of these novel findings regarding the role of treatment context or setting for the treatment and long-term outcome of behavior disorders.

Emergent Control of Manual and Vocal-Motor Activity in Relation to the Development of Speech

Babbling typically precedes, resembles, and conceivably facilitates development of speech, and yet there is no accepted neurobiological characterization of babbling. Here we report a study of infants′ developing control of vocal behavior in relation to manual activity performed under differing conditions of audibility. We hypothesized that babbling is associated with the onset of left-lateralized motor control, as expressed in repetitive right-handed activity, and that audibility facilitates such activity, Sixty-one normally developing infants were seen before (N = 21) or at various intervals following (N = 40) the onset of babbling. In experimental trials, audible or inaudible rattles were placed in left or right hands equally often. Analysis of manual activity revealed little shaking movement in the youngest and vocally least differentiated infants, and a sharp increase in shaking in slightly older infants who had recently begun to babble. Surprisingly, audibility only marginally enhanced shaking activity. A dextral bias was evident in the shaking of infants who had recently begun to babble, but not in younger or older infants. These and other findings suggest that the left cerebral hemisphere may be disproportionately involved in the production of repetitive vocal-motor activity as occurs in babbling.     

MANIPULATION OF POTENTIAL PUNISHMENT PARAMETERS IN THE TREATMENT OF SELF-INJURY1

The self-injurious behavior (SIB) of a blind, profoundly retarded male was observed within a field setting as multiple forms of punishment were applied. The effects of hair-tug punishment were first systematically examined, then hair-tug and electric shock punishment were administered in varing ratios (of punishment deliveries per SIB response) supplemented by continuous restraint contingencies and made contingent on recurrent antecedents of SIB cycles. Treatments were applied over six months of consecutive daily sessions ranging from 30 min to 8 hr duration. Posttreatment followup observations were taken 12, 24, and 34 months after treatment. Partial suppression was produced as a direct function of hair-tug punishment in the initial phase. A generally progressive decrement was produced on already lowered SIB rates with the succeeding components of the treatment package. Extended periods of total SIB suppression occurred as punishment was rendered contingent on antecedent components of each SIB response cycle. Followup observations of nearly 3 yr duration indicated total suppression generalized over all settings in which the subject functioned. The findings were related to the contrasting limits prevailing in most reports of punishment-based SIB suppression.     

System-justifying ideologies and academic outcomes among first-year Latino college students

The present study examines the relationship between system-justifying ideologies and academic outcomes among 78 first-year Latino college students (21 men, 57 women, mean age = 18.1 years) attending a moderately selective West Coast university. Endorsement of system-justifying ideologies was negatively associated with grade point average (GPA); however it was positively associated with feelings of belonging at the university. In addition, system-justifying ideologies were negatively associated with perceptions of personal discrimination. In contrast, ethnic identity centrality was unrelated to GPA, feelings of belonging, and perceptions of personal discrimination once the relationship between system-justifying ideologies and these outcomes was statistically taken into account. The results of the present study suggest that endorsement of system-justifying ideologies may be a double-edged sword for Latino college students, involving trade-offs between academic success and feelings of belonging.     

An online measure of thought suppression

An online thought-suppression paradigm was developed to test predictions of ironic process theory. Participants concentrated on or suppressed a particular semantic category. Semantic activation was indexed by the latency to name words from the category. In Experiments 1 and 2, an analog intrusion was introduced while participants were trying to suppress the information. Results consistent with ironic process theory were observed using words with polar opposites in Experiment 1 and words without polar opposites in Experiment 2. To determine whether these effects were dependent on the analog intrusion, Experiment 3 replicated Experiment 1 without the intrusion. Concentration generated semantic activation, but suppression exacerbated this activation. The data imply that hyperaccessibility results from efforts to suppress, whereas the processes of thought suppression identified by ironic process theory require the presence of material inconsistent with a desired cognitive state.     

Negative self-efficacy and goal effects revisited

The authors address the verification of the functional properties of self-efficacy beliefs and document how self-efficacy beliefs operate in concert with goal systems within a sociocognitive theory of self-regulation in contrast to the focus of control theory on discrepancy reduction. Social cognitive theory posits proactive discrepancy production by adoption of goal challenges working in concert with reactive discrepancy reduction in realizing them. Converging evidence from diverse methodological and analytic strategies verifies that perceived self-efficacy and personal goals enhance motivation and performance attainments. The large body of evidence, as evaluated by 9 meta-analyses for the effect sizes of self-efficacy beliefs and by the vast body of research on goal setting, contradicts findings (J. B. Vancouver, C. M. Thompson, & A. A. Williams, 2001; J. B. Vancouver, C. M. Thompson, E. C. Tischner, & D. J. Putka 2002) that belief in one's capabilities and personal goals is self-debilitating.
