Support networks of adolescent mothers: Effects on parenting experience and behavior

The relation between social support and lower-income African-American adolescent mothers' parenting experience, parenting behavior, and psychological symptoms was studied. Larger support networks were associated with better maternal adjustment unless individuals providing support were also providers of conflict. The young women's own mothers were their most prominent providers of support, and the number of different types of support the grandmother provided was related positively to quality of the adolescent's parenting behavior, but negatively to her experience of parenting. Having more friends in the network was related to better parenting behavior, but having more siblings in the network was related to poorer parenting behavior as well as more psychological symptoms. Although most of the young women relied on male partners for support, no variables related to provision of support by male partners were correlated with maternal adjustment.     

Stagnation and generativity: structure, validity, and differential relationships with adaptive and maladaptive personality

Erikson's concepts of stagnation and generativity were investigated in two studies. Study 1 (N=457) yields two important results. First, it revealed that a model in which stagnation and generativity load on a separate dimension showed a significantly better fit to the data than a one-dimensional model. Second, the stagnation and generativity measures were valid predictors of parental behavior. In Study 2 (N=191), the relationships between stagnation and generativity and the dimensions underlying comprehensive measures of personality were investigated. It was found that stagnation was strongly related to Neuroticism, Extraversion, and Openness to Experience, whereas generativity bore strong relationships with Extraversion, Conscientiousness, and Openness to Experience. In the discussion, stagnation is distinguished from several related variables and a profile of the stagnant individual is constructed and compared with the generative individual. Finally, the interaction between stagnation and generativity in producing specific outcomes is discussed.     

Teachers' perceptions of the frequency and seriousness of violations of ethical standards

Despite nationwide efforts to professionalize public-school teaching, little attention has been given to the matter of standards of professional conduct for teachers. The authors examined teachers' perceptions of the frequency and seriousness of different categories of teacher misconduct. They administered a 34-item questionnaire to 235 school professionals in northwestern South Carolina. For each item, respondents rated the extent to which they agreed or disagreed that the behavior occurred frequently and represented a serious violation of professional ethics. Factor analysis of the ratings of seriousness yielded 3 domains of ethical concerns: (a) student-teacher boundary violations, (b) carelessness in behavior, and (c) subjectivity in grading and instruction. Teachers rated boundary violations as the most serious but least common violations and carelessness in behavior as the most frequent but least serious violation. Problems of subjectivity in grading were rated as moderately frequent and moderately serious. The authors found no differences between male and female teachers or between elementary and secondary teachers in their ratings of the seriousness or frequency of any of the 3 groups of ethical concerns. The authors discuss implications for development of a national code of teacher conduct.     

Validity of self-efficacy scale scores for a Spanish sample

This study analyzed the validity of the Sherer, et al. Self-efficacy Scale for a Spanish sample of 555 subjects, 257 men and 298 women. 415 were from the general population; 34 schizophrenics and 45 with eating disorders were from a clinic, plus 61 drug addicts from two centers. All met DSM-IV-R criteria. The Eysenck Personality Questionnaire, State-Trait Anxiety Inventory, Assertiveness Inventory, and the Self-control Questionnaire were administered. The reliability for total scores, general factor were high even when social self-efficacy was low. A bidimensional factor structure seemed more acceptable. The Self-efficacy scale scores correlated with those on the Self-control Questionnaire and the Assertiveness Inventory. Extraversion scores on the Sincerity dimension of the Eysenck Personality Questionnaire correlated with scores on the State-Trait Anxiety Inventory and Eysenck's Neuroticism and Psychoticism scales. Significant mean differences appeared between the general population group and the three clinical groups. These analyses support the usefulness of the scale for clinical practice and research with Spanish samples.     

Dimensionality of the Pay Satisfaction Questionnaire: a validation study in Belgium

This study examined the underlying dimensions of the Pay Satisfaction Questionnaire to test whether the robust 4-factor structure (Pay Level, Benefits, Raises, and Structure or Administration) often established in the United States can be generalized to other countries and cultures as well. Data of 4 samples (for-profit employees, nonprofit nurses, cultural centre employees, and nonprofit teachers) were analysed with confirmatory factor analyses. The results for the first 3 samples yielded support for the original 4-factor structure of the Pay Satisfaction Questionnaire. In the teachers' sample, the irrelevant Benefits items were excluded from the analysis, resulting in a 3-factor structure of pay satisfaction.     

The race model inequality: interpreting a geometric measure of the amount of violation

An inequality by J. O. Miller (1982) has become the standard tool to test the race model for redundant signals reaction times (RTs), as an alternative to a neural summation mechanism. It stipulates that the RT distribution function to redundant stimuli is never larger than the sum of the distribution functions for 2 single stimuli. When many different experimental conditions are to be compared, a numerical index of violation is very desirable. Widespread practice is to take a certain area with contours defined by the distribution functions for single and redundant stimuli. Here this area is shown to equal the difference between 2 mean RT values. This result provides an intuitive interpretation of the index and makes it amenable to simple statistical testing. An extension of this approach to 3 redundant signals is presented.     

Conceptualizing changes in behavior in intervention research: the range of possible changes model

An international movement has focused on identifying evidence-based interventions that were developed to change psychological constructs and that are supported by controlled studies. However, inconsistent findings within individual intervention studies and among multiple studies raise critical problems in interpreting the evidence, and deciding when and whether an intervention is evidence-based. A theoretical and methodological framework (Range of Possible Changes [RPC] Model) is proposed to guide the study of change in intervention research. The authors recommend that future quantitative reviews of the research literature use the RPC Model to conceptualize, examine, and classify the available evidence for interventions. Future research should adopt the RPC Model to both develop theory-driven hypotheses and conduct examinations of the instances in which interventions may or may not change psychological constructs.     

The effect of SpeechEasy on stuttering frequency in laboratory conditions

The effect of SpeechEasy on stuttering frequency during speech produced in a laboratory setting was examined. Thirteen adults who stutter participated. Stuttering frequencies in two baseline conditions were compared to stuttering frequencies with the device fitted according to the manufacturer's protocol. The fitting protocol includes instructions for deliberate use of vowel prolongation. Relative to the initial baseline condition, stuttering was reduced by 74%, 36%, and 49% for reading, monologue, and conversation, respectively. In comparison, stuttering was reduced by 42%, 30%, and 36%, respectively with the device in place, but before participants were instructed to deliberately prolong vowels. Examination of individual response profiles revealed that although stuttering reduced in the device compared to the baseline conditions during at least one of three speech tasks for most participants, degree and pattern of benefit varied greatly across participants. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) discuss recent research in altered auditory feedback that led to the development of SpeechEasy, (2) analyze and describe issues related to evaluating the treatment benefits of fluency aids, and (3) summarize the range of outcomes that were observed with SpeechEasy in this study.     

Violating equality in social dilemmas: emotional and retributive reactions as a function of trust, attribution, and honesty

In social dilemmas, equality is an important coordination rule. When equality is violated, people seek explanations. In Experiment 1, the authors assessed dispositional trust and found that especially high trusters were affected by the given explanation. High trusters reacted less negatively to external than internal explanations. Experiment 2, using a manipulation of trust in others, revealed a similar pattern across a wider range of negative emotions. In Experiment 3, the authors only induced high trust and showed that when the external explanation turned out to be a lie, emotional and retributive reactions became more negative. Moreover, attribution information did not influence reactions when participants realized that the information was dishonest.
