Self-Rating of religiosity (SRR) in Iran: validity,reliability, and associations with the Big Five

ABSTRACT

The present research aimed to examine the psychometric properties of the Self-Rating of Religiosity (SRR) in Iran. In addition, the associations between the Persian version of this single-item measure of religiosity and the Big Five personality dimensions were investigated. Study 1 (n?=?51) suggested that the Persian translation of the SRR had adequate test-retest reliability over a three-week period. Study 2 (n?=?228) provided evidence for good convergent validity of the SRR, indexed by strong positive associations with scores on the Duke University Religion Index (DUREL). The Big Five dimensions of personality were measured using the Ten-Item Personality Inventory (TIPI). Moreover, the scores on the SRR were positively associated with Agreeableness (r?=?.23, p?<?.01) and Conscientiousness (r?=?.16, p?<?.05), while negatively associated with Openness to Experience (r?=??.25, p?<?.01). These findings are in line with cross-cultural findings on personality correlates of intrinsic religiosity. Limitations and future directions are discussed.     

Effects of reversible inactivation of locus coeruleus on long-term potentiation in perforant path-DG synapses in rats

The locus coeruleus (LC) is the main source of noradrenergic innervations to the forebrain and the hippocampal formation but does not receive noradrenergic projections itself. Previous studies have suggested that hippocampal neural response is modulated by the noradrenergic pathway and that the experimental activation of the LC can potentiate hippocampal responses. Most studies have suggested that the noradrenergic system has controversial effects on long-term potentiation (LTP) in hippocampal neurons, because its influence on synaptic plasticity in perforant path-DG synapses is ambiguous. The aim of this article was to study the LC's role in baseline activity and LTP in perforant path-DG cells of hippocampus by in vivo LC inactivation. Rats were anesthetized with urethane, and LC was temporarily suppressed by intra-LC injection of lidocaine. Population spike (PS) amplitude and excitatory postsynaptic potential (EPSP) slope in DG were recorded 10 min before and 5, 10, 20, 40, 60, and 120 min after tetanization (400 Hz). Saline or lidocaine was injected during the baseline recording (experiment 1), 5 min before tetanus (experiment 2), and 5 min after tetanus (experiment 3). The results from this study indicated that the LC inactivation has no effect on baseline activity of granular cells or maintenance of LTP after tetanization. Moreover, LC inactivation before tetanus had no effect on LTP induction but decreased PS-LTP amplitude 60 and 120 min after tetanization. Taken together, the LC noradrenergic system likely influences LTP induction in later time periods while it has no effect on LTP in earlier time periods.     

Reliability and validity of the Oxford Happiness Inventory among university students in Iran

The aim of the present study was to examine the internal reliability, content validity, construct validity, and concurrent validity of the Persian translation/Farsi version of the Oxford Happiness Inventory. The Oxford Happiness Inventory and Fordyce Happiness Inventory were completed by a sample of 727 Iranian university students. Findings confirmed the internal reliability, construct, and concurrent validity of the Oxford Happiness Inventory. Thus, it can be recommended for use as a trait-measure of happiness among Iranian samples.     

ALTERING THE NEAR‐MISS EFFECT IN SLOT MACHINE GAMBLERS

This study investigated the potential for recreational gamblers to respond as if certain types of losing slot machine outcomes were actually closer to a win than others (termed the near‐miss effect). Exposure to conditional discrimination training and testing disrupted this effect for 10 of the 16 participants. These 10 participants demonstrated high percentages of conditional discrimination testing performance, and the remaining 6 participants failed the discrimination tests. The implications for a verbally based behavioral explanation of gambling are presented.     

Natural teeth and cognitive function in humans

A number of neurobiological, psychological and social factors may account for cognitive impairment. In animal studies a relation between dental status and cognitive performance has been found. It is unclear whether such a relation exists for humans. In a first step we compared the performance of 1,351 participants (53% women, 47% men; age M = 54.0) with natural teeth to 487 edentulous participants (59% women, 41% men; age M = 71.3) on 12 cognitive tests. The natural teeth group had a lower mean age, fewer women, more years of education, higher mini-mental state (MMSE), and performed significantly higher on several cognitive tests. In a subsequent analysis, the cognitive performance of a subset of the participants (50-85 years) was examined. In this analysis, 211 had natural dentition and 188 were edentulous. The groups were matched for gender, age, social variables, diseases, stress and MMSE. The cognitive disadvantage of the edentulous group was still apparent. The results suggest that functional natural teeth relate to relatively preserved cognitive functioning in older age.     

Responsiveness of measures of attentional bias to clinical change in social phobia

This study examined responsiveness of the dot probe measure of attentional bias to standard cognitive-behaviour group therapy (CBGT) for social phobia. People who met criteria for social phobia were randomly allocated to either an immediate treatment condition or a waiting list control (WLC). All participants completed self-report measures of social anxiety, depression, and anxiety sensitivity, a verbal dot probe and a facial dot-probe task before and after eight weeks of standard CBGT was undertaken by the treatment group. On the first measurement occasion the two groups had similar scores on all measures. On the second measurement occasion the self-report scores for the CBGT group were lower than those of the WLC group. Performance on the dot-probe tasks for the CBGT group had also changed. The treatment group appeared to direct their attention away from social threat words and threatening faces after CBGT.     

A Comparison of Effectiveness of Dohsa‐hou and the Alexander Technique on Happiness,Social Adjustment,Hope, Mental Health,and Quality of Life in Patients with Parkinson's Disease

The purpose of this study was to compare the effectiveness of Dohsa‐hou and the Alexander Technique on happiness, social adjustment, hope, mental health, and quality of life in patients with Parkinson's disease. The statistical population of this study included all of the patients with Parkinson's disease who were clients of neural therapeutic centers in Isfahan City in 2015. Among this population, 28 patients were selected through convenience sampling as the sample of the study. The Oxford Happiness Questionnaire, the Social Adjustment Scale, the Adult Hope Scale, the General Health Questionnaire, and the Word Health Quality of Life Questionnaire were used as the instruments of the study. Data were analyzed by analyses of variance with repeated measures. The results showed that both interventions of this study can improve happiness, hope, and quality of life in patients with Parkinson's disease, but Dohsa‐hou is more effective than the Alexander Technique in the improvement of happiness and hope. Probable explanations have been discussed.     

When white collar criminals turn to fatal violence: The impact of narcissism and psychopathy

The present article takes as its point of departure Perri's view, according to whom the impact of personality traits such as psychopathy and narcissism has unduly been omitted in research on white collar criminality. However, this article argues that although such factors have an important role to play in some cases when white collar criminals turn violent in order to prevent the detection of their felonies, they constitute neither the necessary nor the sufficient conditions for white collar criminals to commit murders. This means on the one hand that, although potentially increasing the risk for violence, these traits are not by themselves sufficient as the triggers of violent acts and can function so only under certain social‐contextual circumstances. However, such personality traits are not by themselves necessary, as there can be empirical cases of fraud detection murder committed by white collar criminals lacking them. This position is supported by both a logical analysis of Perri's main arguments and by empirical evidence, consisting of a few real‐life cases of Scandinavian white collar criminals who have “turned red.”     

The Factor Structure of the Twelve Items General Health Questionnaire (GHQ-12): a Population Based Study

Mental health is a key component of general health based on world health organization (WHO) definition of health. A short form of the general health questionnaire (GHQ-12) has been widely used as an assessment tool of general and mental health. This study was designed to evaluate the properties of the Persian version of this questionnaire. Of 6140 subjects aged 10–90 years of a cohort study of Northern Iran, the relevant data of 5074 individuals aged ≥18 years were considered for analysis. Confirmatory factor analysis was conducted to evaluate the six models including one-dimensional model, one-dimensional model with correlated errors on negative items, two-dimensional model based on negative and positive statement items, two-dimensional model based on social dysfunction and psychological distress, three-dimensional model based on anxiety/depression, social dysfunction and loss of confidence and finally one-dimensional model with an additional factor for the negatively phrased items. The best fit indices belonged to one-dimensional model with correlated errors on negative items with χ2 = 686.8, df = 39, CFI = 0.953, RMSEA = 0.057 (95%CI: 0.054–0.061), SRMR = 0.0317, AGFI = 0.952, TLI = 0.920 and AIC = 764.8 and also three-dimensional model with χ2 = 860.7, df = 51, CFI = 0.941, RMSEA = 0.056 (95%CI: 0.053–0.059), SRMR = 0.0343, AGFI = 0.955, TLI = 0.923 and AIC = 915.0. In the comparison between these two best models we had ?χ2 = 174.2, ?df = 12, p-value < 0.001 in favor of the one-dimensional model. One-dimensional model with correlated errors on negative items showed the best fitting indices with our population.
