A systematic review of work-place interventions for alcohol-related problems

AIMS The aims of this study were to (1) gauge any improvement in methodological quality of work-place interventions addressing alcohol problems; and (2) to determine which interventions most effectively reduce work-place-related alcohol problems. METHODS A literature search was undertaken of the data bases, Ovid Medline, PsychINFO, Web of Science, Scopus, HSELINE, OSHLINE and NIOSHTIC-2 for papers published between January 1995 and September 2007 (inclusive). Search terms varied, depending on the database. Papers were included for analysis if they reported on interventions conducted at work-places with the aim of reducing alcohol problems. Methodological adequacy of the studies was assessed using a method derived from the Cochrane Collaboration guidelines. RESULTS Ten papers reporting on work-place alcohol interventions were located. Only four studies employed randomized controlled trials (RCT), but all these had methodological problems. Weaknesses in all studies related to representativeness of samples, consent and participation rates, blinding, post-test time-frames, contamination and reliability, and validity of measures used. All except one study reported statistically significant differences in measures such as reduced alcohol consumption, binge drinking and alcohol problems. CONCLUSIONS The literature review revealed few methodologically adequate studies of work-place alcohol interventions. Study designs, types of interventions, measures employed and types of work-places varied considerably, making comparison of results difficult. However, it appears from the evidence that brief interventions, interventions contained within health and life-style checks, psychosocial skills training and peer referral have potential to produce beneficial results.

The effects of gender on diagnosis of psychological disturbance

This research examines the effect of patient gender on the detection of psychological disturbance. In Study 1, primary-care patients were requested to complete the General Health Questionnaire (GHQ), a measure of nonpsychiatric psychological disturbance, prior to their consultation. The patients GHQ score was compared with physician judgments about the level of disturbance in that patient (N=1913). Although there were a similar number of GHQ high scorers among males and females, the physicians classified significantly more females than males as disturbed. The doctors classified as disturbed a larger proportion of nondisturbed women than nondisturbed men. In order to explore the behavior of recent medical graduates, Study 2 examined the detection behavior of interns in an outpatient department with 384 of their patients. The interns behaved in a similar manner to the primary-care physicians.

The reliability and stability of a quantity-frequency method and a diary method of measuring alcohol consumption

The study aimed to assess the test-retest reliability of two commonly used measures of alcohol consumption, the quantity-frequency (QF) method and the diary method, as well as the stability of scores on the two measures over time. Two methods of assessing reliability and stability were employed. The first was a traditional method based on calculation of correlation coefficients for agreement between scores on repeated measures over a short retest interval to yield test-retest reliability coefficients, and over a long retest interval to yield stability coefficients. The second method was that devised by Wiley and Wiley (1970) to differentiate the effects of reliability and stability on repeated measures over time. The two methods were applied to a sample of heavy drinkers and to a sample of light drinkers. The results indicated that both the QF and diary measures are reliable in measuring alcohol consumption of light drinkers. Both measures are less reliable for heavy drinkers. The results indicate, in addition, that drinking consumption levels of light drinkers demonstrate a high degree of stability. However, the consumption levels of heavy drinkers demonstrate less stability, especially over a long time period. Heavy drinkers significantly reduced reported levels of alcohol consumption on both measures after the first test, suggesting a regression to the mean effect or the possibility of unintended intervention effects due to repeated measurement of drinking behaviour.

Differences in licensee, police and public opinions regarding interventions to reduce alcohol-related harm associated with licensed premises

Objectives: To determine the level of support by licensees, police and the general public for interventions to reduce alcohol‐related harm associated with licensed premises and to identify differences between the three groups.
