Odor identification impairments in schizophrenia: relationship with demographic measures, clinical variables, and diagnostic subtypes

Smell identification deficits are consistently found in schizophrenia (SZ), but little is known about the nature and characterization of this deficit or its relationship to the phenomenology of the illness. This study aims to further delineate smell identification errors in SZ by examining the relationship of patient demographic differences with smell-identification performance. Our results showed that a patient's gender and education were related to odor-identification scores, with better performance seen in female patients and in those with greater educational attainment. However, there was no effect related to age, ethnicity, or socioeconomic status on odor identification. A smell identification deficit was also unrelated to clinical characteristics of the patients, including age at first hospitalization, number of psychiatric hospitalizations, and duration of illness. Odor identification also did not differ by SZ subtype, nor between SZ and schizoaffective disorder patients. These findings emphasize that odor identification deficits in SZ are unrelated to clinical illness features, cannot be explained by other confounds related to olfaction in the general population, and may be core features related to the SZ disease process.     

Life Stressors, Social Support, and Depressive Symptoms Among First-Time Welfare Recipients

This paper examines the associations among stressful life events, social support, and depressive symptoms in a sample of 580 first-time welfare recipients. Self-reported number of depressive symptoms was greater than in corresponding community samples. Stressors and social supports made independent main effect contributions to depressive symptoms in a multiple regression analysis. Women with transportation barriers to employment, those experiencing greater numbers of stressful life events, and those who were less satisfied with their housing situation reported greater numbers of depressive symptoms. In contrast, women who were more satisfied with their social support and those with higher attendance at religious services reported fewer depressive symptoms. Implications for welfare reform policy and programs are discussed.     

Motivation for agreement with parental values: desirable when autonomous,problematic when controlled

Two studies examined the well-being and parenting correlates of autonomous and controlled motivations for agreement with parental values. We hypothesized that autonomous motivation would be associated with subjective well-being, whereas controlled motivation would be associated with agitation and guilt. Study 1 involved 399 Israeli youth (mean age = 23.8) and Study 2 involved 131 Israeli adolescents (mean age = 16.9). Results of both studies supported the hypotheses. The findings suggest that only autonomous motivation for agreement with parents’ values is positively associated with well-being. This effect is over and above the extent of agreement between offspring values and perceived parents’ values, and highlights the importance of distinguishing between autonomous and controlled endorsement of values.     

Mediation and moderation of the effects of watching the angiography screen on patients

It has been reported that allowing patients to watch the coronary angiography screen during the procedure results in psychological benefits. This study aimed to investigate the roles of illness perceptions as mediators of this outcome and to examine whether individual differences in monitoring coping style moderated these effects. The experiment compared patients who were instructed to watch the monitor screen (n = 57) with those who were not (n = 51). Questionnaires were used to measure the research variables at one day and one month after the procedure. Results showed that watching the angiography screen increased patients’ personal and treatment control perceptions that mediated changes in self-assessed health, risk perceptions, negative affect, general and diet outcome expectancies, and diet and physical activity intentions. The behavior-related outcomes were moderated by monitoring coping style. These findings illustrate the significance of illness perceptions, perceived control and monitoring coping style in achieving desirable outcomes among patients undergoing coronary angiography, and reveal opportunities for interventions using medical imaging technologies.     

A failure to replicate rapid syntactic adaptation in comprehension

Language comprehension requires successfully navigating linguistic variability. One hypothesis for how listeners manage variability is that they rapidly update their expectations of likely linguistic events in new contexts. This process, called adaptation, allows listeners to better predict the upcoming linguistic input. In previous work, Fine, Jaeger, Farmer, and Qian (PLoS ONE, 8, e77661, 2013) found evidence for syntactic adaptation. Subjects repeatedly encountered sentences in which a verb was temporarily ambiguous between main verb (MV) and reduced relative clause (RC) interpretations. They found that subjects who had higher levels of exposure to the unexpected RC interpretation of the sentences had an easier time reading the RC sentences but a more difficult time reading the MV sentences. They concluded that syntactic adaptation occurs rapidly in unexpected structures and also results in difficulty with processing the previously expected alternative structures. This article presents two experiments. Experiment 1 was designed as a follow-up to Fine et al.’s study and failed to find evidence of adaptation. A power analysis of Fine et al.’s raw data revealed that a similar study would need double the items and four times the subjects to reach 95% power. In Experiment 2 we designed a close replication of Fine et al.’s experiment using these sample size guidelines. No evidence of rapid syntactic adaptation was found in this experiment. The failure to find evidence of adaptation in both experiments calls into question the robustness of the effect.     

The Relational Structure of Human Dignity

This article argues that received accounts of the concept of human dignity face more difficulties than has been appreciated, when explaining the connection between human dignity and the duty of respect that dignity is supposed to generate. It also argues that a novel, relational, account has the adequate structure to explain such connection.     

Family functioning among returnees to Orthodox Judaism in Israel

The role of religious conversion in marriages and family functioning has been little explored. The current study examined family functioning and parenting stress among returnees to Orthodox Judaism with adolescent children. Possible explanatory factors for difficulties, such as attachment insecurity, religious discord in families, and poor community integration, were also explored. Randomly selected samples of returnee and nonreturnee Orthodox Jews with adolescent children (N = 1632) completed measures of attachment, community integration, marital functioning, and parenting stress. Results indicate that returnees report greater family disengagement (lack of warmth), family chaos (lack of control), and parenting stress. They also reported higher religious discord, higher attachment insecurity, and poorer community integration, which all correlated with higher parenting stress, family disengagement (lack of warmth), and family chaos (lack of control). Moreover, differences between returnees and nonreturnees on family functioning and parenting stress were largely mediated by differences in the explanatory factors. These results substantiate previous anecdotal reports and suggest possible avenues for intervention among Orthodox returnees with family difficulties. They also support the relevance of religious factors in family functioning.     

Psychometric properties of an experimental test for the assessment of basic arithmetic calculation efficiency / Propiedades psicométricas de una prueba experimental para la evaluación de la eficacia del cálculo aritmético básico

Abstract

In this article the ‘Arithmetic Calculation Efficiency Test’ (Test de Eficacia en el cálculo aritmético – TECA), a test for the assessment of arithmetic efficiency in terms of precision and speed in school-aged subjects, is introduced. The test aims to contribute to educational practices and the diagnosis of students who are at risk of Learning Difficulties in Calculations (LDC). Psychometric properties of the test items were analysed based on a sample of 331 subjects from grade 1 to 6 from Primary School. Analysis of content validity, item analysis, dimensionality and reliability have provided evidence of the validity of a one-dimensional structure consistent with the theoretical framework.
