Overt and covert aggression and negative emotion in the workplace

This study explores indirect and direct aggression, emotion and aggressive behaviour in a male-dominated organisation, an Australian police force (APF). The study examines women’s experience of direct/overt and indirect/covert aggression in the workplace and whether their experience of aggression is higher in the presence of men than of other women; also, whether men’s experience of negative emotions is directly associated with their reported aggressive behaviour towards women. The study formed part of a larger project in which 144 women and 159 men employed in the APF completed a questionnaire. Results are discussed in terms of their theoretical and practical implications, and suggestions are made for future research into this important but difficult subject area.

The bipolar depression rating scale (BDRS) : its development, validation and utility

Objectives: Unipolar and bipolar depression differ neurobiologically and in clinical presentation. Existing depression rating instruments, used in bipolar depression, fail to capture the necessary phenomenological nuances, as they are based on and skewed towards the characteristics of unipolar depression. Both clinically and in research there is a growing need for a new observer-rated scale that is specifically designed to assess bipolar depression.

Methods: An instrument reflecting the characteristics of bipolar depression was drafted by the authors, and administered to 122 participants aged 18–65 (44 males and 78 females) with a diagnosis of DSM-IV bipolar disorder, who were currently experiencing symptoms of depression. The Bipolar Depression Rating Scale (BDRS) was administered together with the Hamilton Depression Rating Scale (HAM-D), Montgomery Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS).

Results: The BDRS has strong internal consistency (Cronbach's alpha = 0.917), and robust correlation coefficients with the MADRS (r = 0.906) and HAM-D (r = 0.744), and the mixed subscale correlated with the YMRS (r = 0.757). Exploratory factor analysis showed a three-factor solution gave the best account of the data. These factors corresponded to depression (somatic), depression (psychological) and mixed symptom clusters.

Conclusions: This study provides evidence for the validity of the BDRS for the measurement of depression in bipolar disorder. These results suggest good internal validity, provisional evidence of inter-rater reliability and strong correlations with other depression rating scales.

Poor agreement between self-reported diagnosis and bone mineral density results in the identification of osteoporosis.

Osteoporosis is a major health concern, estimated to affect millions worldwide. Bone mineral density (BMD) assessment is not practical for many large-scale epidemiological studies resulting in the reliance of self-report methods to ascertain diagnostic information. The aim of the study was to assess the validity of self-reported diagnosis of osteoporosis in a population-based study. This study examined data collected from 906 men and 843 women participating in the Geelong Osteoporosis Study. Osteoporosis was self-reported and compared against results of BMD scans of the hip and spine. Validity was examined by calculating sensitivity, specificity, positive predictive value, negative predictive value, and kappa statistic. Osteoporosis was self-reported by 118 (6.7%) participants and identified using BMD results for 64 (3.7%) participants. Specificity and negative predictive value were good (95.1% and 96.0%, respectively), whereas sensitivity and positive predictive value were poor (35.9% and 31.4%, respectively). The overall level of agreement (kappa) was 0.29. The results changed only slightly when we included participants with osteopenia and adult fracture as osteoporotic. Reliance on self-report methods to ascertain osteoporosis status is not recommended.

Atypical features and treatment choices in bipolar disorders: a result of the National Bipolar Mania Pathway Survey in China.

In this study, we examined the point prevalence rate of atypical features in bipolar disorder, and estimated the potential impact of these features on treatment practices in China. Using the atypical features criteria of the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IV), we documented the atypical symptoms in 3 906 consecutive participants with bipolar disorder enrolled at 26 psychiatric services across China. We further assessed the association between atypical features and the treatment approaches, including the prescription of antidepressants. The overall point prevalence rate of atypical features was 9.1% among patients with various bipolar disorder subtypes. When the definition was broadened to include atypical features B, the overall rate increased to 11.8%. Interestingly, among patients with the mixed state and remission subtypes, there was a significant difference in the rates of antidepressant medication usage between patients who met and those who did not meet the criteria for atypical features B. These findings indicate a trend of using antidepressants for these two types of patients with atypical features. Further, for both mixed state and remission patients, treatment approaches were related to atypical features B. Our findings provide evidence to assist clinicians to readily recognize atypical features in bipolar subtypes and can propose treatments based on these diagnoses.

Exercise counseling to enhance smoking cessation outcomes: the Fit2Quit randomized controlled trial

BACKGROUND: Regular exercise has been proposed as a potential smoking cessation aid.

PURPOSE: This study aimed to determine the effects of an exercise counseling program on cigarette smoking abstinence at 24 weeks.

METHODS: A parallel, two-arm, randomized controlled trial was conducted. Adult cigarette smokers (n = 906) who were insufficiently active and interested in quitting were randomized to receive the Fit2Quit intervention (10 exercise telephone counseling sessions over 6 months) plus usual care (behavioral counseling and nicotine replacement therapy) or usual care alone.

RESULTS: There were no significant group differences in 7-day point-prevalence and continuous abstinence at 6 months. The more intervention calls successfully delivered, the lower the probability of smoking (OR, 0.88; 95 % CI 0.81-0.97, p = 0.01) in the intervention group. A significant difference was observed for leisure time physical activity (difference = 219.11 MET-minutes/week; 95 % CI 52.65-385.58; p = 0.01).

CONCLUSIONS: Telephone-delivered exercise counseling may not be sufficient to improve smoking abstinence rates over and above existing smoking cessation services.
