Sexuality and intimacy following radical prostatectomy: patient and partner perspectives.

Most research on adjustment following radical prostatectomy has focused on limited assessments of urinary and erectile functioning. In this study, the authors provided a more comprehensive assessment of sexuality from 134 radical prostatectomy patients and their partners and determined the extent to which various components of sexuality are associated with psychosocial adjustment. Measures of sexuality and intimacy modestly predicted patients' emotional distress and quality of life (QoL), with body image and dyadic adjustment playing the most important roles after controlling for medical variables, general physical functioning, and optimistic outlook. Urinary incontinence and other sexuality variables were not unique predictors. In contrast, partner ratings of sexual satisfaction played a more important role in predicting their QoL.     

Equivalence relations and the contextual control of multiple derived stimulus functions

Contextual control is a key aspect in equivalence research to support the claim that stimuli may have multiple functions or symbols may have multiple meanings. The present study investigated the contextual control of multiple derived stimulus functions in two experiments. In Experiment 1, equivalence classes were formed and one stimulus set from each class was used to establish two different functions: one via positive reinforcement (key-pressing) and another via negative reinforcement (button clicking), both under contextual control of two different background colors. Later, other stimuli from the equivalence class were presented on those background colors and contextual control of multiple derived stimulus functions was assessed. Experiment 2 added a third background in which no programmed response was reinforced, that is, responses were extinguished. Transfer-of-function tests revealed contextual control of three different functions, including derived extinction. Implications for equivalence relations as a behavior-analytical model of symbolic functioning are discussed.     

Exploring the integration of thin-ideal internalization and self-objectification in the prevention of eating disorders

Analyses of thin-ideal internalization and self-objectification were conducted within the context of a cognitive dissonance based eating disorder prevention program implemented in an undergraduate sorority. Participants completed self-report assessments at baseline (n = 177), post-intervention (n = 169), 5-month (n = 159), and 1-year follow-up (n = 105). Cross-sectional path analysis indicated that thin-ideal internalization and self-objectification predict each other and both predict body dissatisfaction, which in turn, predicts eating disorder symptoms. A longitudinal examination conducted using hierarchical linear modeling indicated that participants showed significant reductions in thin-ideal internalization, self-objectification, body dissatisfaction, and eating disorder symptoms after participating in the prevention program. Reductions of symptoms were maintained 1-year post-intervention, with the exception of self-objectification, which was significantly reduced up to 5-months post-intervention. Collectively, results suggest that targeting both thin-ideal internalization and self-objectification simultaneously within eating disorder prevention programs could increase the reduction of eating disorder symptoms.     

Contextual interference and augmented feedback: is there an additive effect for motor learning?

Learning to perform a skilled behavior is affected by the context of the practice session and the frequency of augmented feedback. We studied the combined effect of these variables in the acquisition of a ballistic, bi-directional lever movement pattern involving four different target locations as measured by performance in practice, retention, and transfer tests. Augmented feedback was presented in either an every-trial or a faded schedule during random and blocked practice. Consistent with the contextual interference effect, the blocked practice group produced lower errors in acquisition, but the random practice group outperformed the blocked practice group in both retention and transfer. In contrast, faded feedback did not have a beneficial effect on learning and degraded learning when provided during blocked practice. While the results were consistent with previous findings of random and blocked practice, they were not consistent with previous findings of reduced feedback frequencies.     

The contribution of short-term memory for serial order to early reading acquisition: evidence from a longitudinal study

Early reading acquisition skills have been linked to verbal short-term memory (STM) capacity. However, the nature of this relationship remains controversial because verbal STM, like reading acquisition, depends on the complexity of underlying phonological processing skills. This longitudinal study addressed the relation between STM and reading decoding acquisition by distinguishing between STM for item information and STM for order information based on recent studies showing that STM for item information, but not STM for order information, recruits underlying phonological representations. If there is a specific link between STM and reading decoding acquisition, STM for order information should be an independent predictor of reading decoding acquisition. Tasks maximizing STM for serial order or item information, measures of phonological abilities, and reading tests were administered to children followed from kindergarten through first grade. We observed that order STM capacity, but not item STM capacity, predicted independent variance in reading decoding abilities 1 year later. These results highlight the specific role of STM for order in reading decoding acquisition and argue for a causal role of order STM capacity in reading acquisition. Mechanisms relating STM for order information and reading acquisition are discussed.     

The Difficulties in Emotion Regulation Scale: Factor Structure and Association with Nonsuicidal Self-Injury in Adolescent Inpatients

Research suggests that difficulties in emotion regulation are an important correlate of nonsuicidal self-injury (NSSI) in adults. Research examining this link in adolescents is limited by the lack of comprehensive instruments to assess difficulties in emotion regulation. Against this background, the aims of the current study were to (a) confirm the six-factor structure of the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, Journal of Psychopathology and Behavioral Assessment, 23(4), 253?C263, 2004) in a sample of adolescent inpatients (N?=?218); (b) explore the relation between different aspects of emotion dysregulation and lifetime NSSI while controlling for psychopathology and sex; and (c) assess the clinical utility of the DERS in detecting lifetime NSSI status. Fit indices obtained through Confirmatory Factor Analysis indicated that the six-factor structure of the DERS fit the data adequately and that most items loaded strongly on their respective latent factor. All six latent factors were significantly correlated with each other, with the exception of lack of emotional awareness and difficulties engaging in goal-directed behavioral when distressed. Regression analyses revealed that only the limited access to emotion regulation strategies subscale accounted for a significant portion of the variance in NSSI when controlling for other aspects of emotion dysregulation, sex, and psychopathology. Receiver Operating Characteristic analysis indicated that the DERS limited access to emotion regulation strategies subscale score has moderate diagnostic accuracy in detecting the presence of NSSI. The optimal cut-off score was 21.5 when detecting NSSI among inpatient adolescents. Results provide further support for the relation between emotion regulation difficulties and NSSI. The DERS appears to be a useful measure of detecting NSSI in clinical samples of adolescents.     

Optimism and Prostate Cancer-Specific Expectations Predict Better Quality of Life after Robotic Prostatectomy

We examined the relations among generalized positive expectations (optimism), prostate-cancer specific expectations, and prostate cancer-related quality of life in a prospective sample of 83 men who underwent robotic assisted laparoscopic prostatectomy (RALP) for prostate cancer. Optimism was significantly associated with higher prostate cancer-specific expectations, β = .36, p < .001. In addition, optimism and prostate cancer-specific expectations were independent prospective predictors of better scores on the following prostate cancer-related quality of life scales: Sexual Intimacy and Sexual Confidence; Masculine Self-Esteem (specific expectations only), Health Worry, Cancer Control, and Informed Decision Making (βs > .21, ps < .05). When considered simultaneously, both optimism and specific expectations contributed uniquely to better Health Worry and Cancer Control scores, optimism was a unique predictor of better Sexual Intimacy and Sexual Confidence scores, and specific expectations uniquely predicted higher scores on Informed Decision Making. Although optimism and prostate-cancer specific expectations are related, they contribute uniquely to several prostate cancer-related quality of life outcomes following RALP and may be important targets for quality of life research with this population.     

The Adolescent Behavior Checklist: Validation Using Structured Diagnostic Interviews

The purpose of this study was to evaluate the discriminant validity of scores from the Adolescent Behavior Checklist (ABC), a self-report measure of ADHD symptomatology for adolescents ages 11–17 years. Validity was assessed through correlational, univariate, and discriminant function analyses using three groups: (1) adolescents diagnosed with ADHD, (2) adolescents currently experiencing a mood and/or anxiety disorder, and (3) adolescents with no major psychological disorder. Convergent and divergent validity of the ABC factor scores was demonstrated through correlational results with (1) parent and adolescent report of ADHD symptoms during structured psychiatric interviews and (2) scores on questionnaires measuring related and nonrelated constructs. Univariate analyses indicated that the ADHD group obtained significantly higher scores than did the nonclinical adolescents across all ABC factors. Additionally, the ADHD group scored significantly higher than did the psychiatric controls on the following ABC factors: Conduct Problems, Impulsivity/Hyperactivity, and Social Problems. Results from discriminant analyses supported the reliability of ABC scores in correctly classifying participants into groups. Compared to the Youth Self-Report, the ABC was found to be somewhat better at classifying when used in a multiinformant discriminant analysis. Therefore, overall results from the current study suggest that the ABC is a valid and useful self-report screening measure for ADHD symptoms and related difficulties.     

Hispanic adolescent pregnancy testers: a comparative analysis of negative testers, childbearers and aborters.

Fifty-six Hispanic adolescents who requested a pregnancy determination at a municipal outpatient adolescent clinic participated in a comparative study of negative testers, childbearers, and aborters. The study's purposes were to assess differences between negative and positive pregnancy testers and to evaluate the pregnancy resolution decision-making process of positive testers. Data were collected using a two-part structured interview administered prior to and following knowledge of pregnancy test results. Results indicated that negative and positive pregnancy testers were similar in all areas evaluated. However, positive testers were slightly older and had higher self-esteem than negative testers. Of the 36 positive testers, 29 chose to deliver and keep the baby. None of the adolescents chose adoption. Adolescents were consistent in their pregnancy resolution decision before and after knowledge of pregnancy test results. The pregnant adolescents considered themselves to be the most influential person in the decision-making process. There were no significant differences between the childbearers and the aborters, although the former demonstrated higher self-esteem and greater religiosity. Most of the teenagers were at risk for unintended pregnancy; therefore, subsequent family planning counseling efforts should be directed at this population.     

Indirect majority and minority influence: An exploratory study

In a 2 × 2 design, 85 subjects were asked to estimate the size of angles (direct influence) that were either 90 or 85°, after being confronted with incorrect judgements of a majority (88 per cent) or a minority (12 per cent) of people estimating the angles at 50°. Additionally, pre- and post-test measures were used to establish indirect influence on subjects' judgements pertaining to acute angles (i.e. on the estimation of the length of lines constituting the angles, and on the imaginary weight of figures represented by these angles). Overall, little direct influence is observed. This may partly be due to the introduction of a denial of the credibility of the source in all conditions. In fact, some evidence of direct influence is only found in the majority–85° angles condition. An instance of indirect influence (on the estimation of length of lines) appeared as the result of a majority stance when the angles in the experimental phase were 90°. When these angles were 85°, indirect minority influence (on the estimation of weight of figures) was observed. These effects had been predicted on the basis of the hypothesis stating that indirect majority influence would be possible when subjects expected consensus on the correct response (in the 90° angles condition), without being able to reach consensus at the manifest level (because of the denial and the restriction imposed by the clear shape of 90° angles). Indirect minority influence was hypothesized to be stronger in a situation that allows for diverse responses (i.e. for 85° angles).
