Coping with gastrointestinal endoscopy: self-efficacy enhancement and coping style.

Forty-eight men scheduled for endoscopy were assessed for preferred coping style and assigned to one of four preparation conditions: (a) relaxation plus coping self-efficacy (SE) enhancement, (b) relaxation only, (c) procedural information, and (d) no preparation. It was hypothesized that increases in SE would be associated with better behavioral and self-report assessments of coping with endoscopy, and that coping style would moderate effects of SE enhancement. Hypotheses were largely confirmed. Ss in SE enhancement preparation experienced greater increases in coping SE and greater decreases in distress before and during endoscopy than did other Ss. Changes in coping SE were negatively correlated with changes in anticipatory anxiety, and SE ratings were significantly related to distress during endoscopy. Ss classed as monitors fared most poorly with no-preparation, whereas blunters did most poorly with procedural information.

Early prognosis for low back disability: intervention strategies for health care providers.

PURPOSE: Disability following acute occupational low back pain (OLBP) represents a significant and preventable health outcome, yet confusion about prognostic factors have limited the development of effective, targeted interventions for those at greatest risk. The purpose of this study was to synthesize findings from available studies of prognostic factors for OLBP disability in a clinically-relevant framework. METHOD: A systematic search of the MEDLINE database was conducted to identify empirical studies assessing the value of various prognostic factors to predict extended disability after an acute episode of OLBP. Relevant studies were screened based on a number of inclusionary criteria. Prognostic factors were catalogued, summarized, and evaluated based on agreement across studies, and clinical recommendations were developed based on the evidence. RESULTS: Of 361 studies of OLBP disability found, 22 met specific criteria for inclusion. Significant prognostic factors included low workplace support, personal stress, shorter job tenure, prior episodes, heavier occupations with no modified duty, delayed reporting, severity of pain and functional impact, radicular findings and extreme symptom report. Physicians can decrease OLBP disability by using standardized questionnaires, improving communication with patients and employers, specifying return to work accommodations, and employing behavioural approaches to pain and disability management. Future studies should evaluate interventions guided by prognosis.

Nonprogressing profiles in smoking cessation: what keeps people refractory to self-change?

A 2-year cross-sequential analysis of informal self-change efforts at smoking cessation evaluated the use of coping operations and the mediation of cognitive judgments among four composite profiles. Subjects (N = 544) were grouped by stage of readiness to change (contemplation, action, relapse, and maintenance) and assessed every 6 months on 10 change processes, self-efficacy, and the decisional balance between the "pros" and "cons" of smoking. Two change status profiles, contemplation to maintenance, and relapse to maintenance, were selected as exemplars of optimal linear progress; two others, chronic contemplation and chronic relapse, illustrated nonprogressing patterns in which subjects remained stuck in the same stage for 2 years. Multivariate and univariate ANOVA results indicated that nonprogressing smokers overutilize certain experiential change processes rather than underutilizing behavioral strategies, as was predicted. Implications of these results for specialized self-help interventions are discussed in the context of a comprehensive model of change for the addictive behaviors.

Biomechanical factors affecting upper extremity cumulative trauma disorders in sign language interpreters.

Symptoms associated with upper extremity cumulative trauma disorders (UECTDs) recently have been reported in professional sign language interpreters. The present investigation is a case control study of potential biomechanical factors that may exacerbate or maintain UECTD-related symptoms in this occupational group. Based on the results of a medical screening, interpreters were classified into two groups: working with pain (n = 16) and working without pain (n = 13). There were no significant differences between the groups on age, gender, years signing, years interpreting, and wrist and forearm endurance and flexibility as measured during an isokinetic strength test of the upper extremities. Subjects were exposed to a standard interpreting task. Groups were compared on measures of repetitiveness of hand/wrist motion, work/rest cycle, postural stress, and smoothness of movement. Heart rate, pain, fatigue, and perceived reduction in extremity flexibility also were measured. The group working with pain demonstrated a distinct pattern of potential biomechanical risk factors previously associated with UECTDs in other occupations. By comparison with the control group, those working with pain exhibited fewer rest breaks, more frequent hand/wrist deviations from neutral, more frequent lateral excursions from an optimal work envelope, and more rapid finger/hand movements while interpreting. Significant group differences on self-report measures of pain, fatigue, and perceived limitation in range of motion also were observed. An analysis of heart-rate response to the interpreting task revealed that both groups demonstrated a modest increase in heart rate to the interpreting task, although interpreters working with pain displayed lower heart rates across all phases of the experimental task.(ABSTRACT TRUNCATED AT 250 WORDS)

The relative importance of dispositional optimism and control appraisals in quality of life after coronary artery bypass surgery.

Similar mechanisms have been proposed to explain the stress-buffering effects of both dispositional optimism and perceived control. Yet dispositional optimism as a personal resource should function independently of situational control appraisals. To evaluate the unique and additive contributions to adaptation of control appraisals and optimism, we followed 49 individuals scheduled for coronary artery bypass surgery. One month before surgery dispositional optimism was associated with neither health locus of control nor specific expectancies about the outcomes of surgery. Dispositional optimism, however, was associated with perceived control over the course of the illness and with quality of life appraisals. Although presurgery optimism predicted life quality 8 months after surgery, this was not the case when general and specific control appraisals and specific expectancies were included in the prediction. These findings are discussed as they relate to current conceptions of trait optimism.
