Physician and patient communication training in primary care: Effects on participation and satisfaction.

[Correction Notice: An erratum for this article was reported in Vol 28(2) of Health Psychology (see record 2009-03297-015). There was a typographical error in the text on page 521, in the first sentence of the first full paragraph. The corrected sentence is provided in the erratum.] Objective: To assess the effects of a communication skills training program for physicians and patients. Design: A randomized experiment to improve physician communication skills was assessed 1 and 6 months after a training intervention; patient training to be active participants was assessed after 1 month. Across three primary medical care settings, 156 physicians treating 2,196 patients were randomly assigned to control group or one of three conditions (physician, patient, or both trained). Main Outcome Measures: Patient satisfaction and perceptions of choice, decision-making, information, and lifestyle counseling; physicians' satisfaction and stress; and global ratings of the communication process. Results: The following significant (p     

A model course in social psychology and health.

Describes a model course for social science and premedical undergraduates concerned with interpersonal aspects of psychology as they relate to health and illness. The course is based on (1) the results of a survey of faculty (N?=?112) in medicine and health psychology; (2) the 2-yr teaching experiences of the authors; (3) input of experts in the field; and (4) evaluations from students in psychology, sociology, and the health sciences.

Understanding and assessing nonverbal expressiveness: The Affective Communication Test.

577 undergraduates participated in an investigation of the concept of nonverbal emotional expressiveness. Ss were administered a 13-item self-report Affective Communication Test (ACT) and a battery of other tests, including the Marlowe-Crowne Social Desirability Scale, Taylor Manifest Anxiety Scale, Rotter's Internal–External Locus of Control Scale, and Coopersmith Self-Esteem Inventory. Results show the ACT to be a reliable and valid measure of individual differences in expressiveness/charisma, which is (a) a likely element of social influence in face-to-face interaction, (b) a logical extension of past approaches to a basic element of personality (exhibition), and (c) a valuable construct in approaching current problems in nonverbal communication research.

Structural-equation models of current drug use: Are appropriate models so simple(x)?

The simplex and common-factor models of drug use were compared using maximum-likelihood estimation of latent variable structural models in two samples: a sample of 226 high school students, using ratio-scale measures of current drug use, and a sample of 310 industrial workers and 811 college students, using ordinal-scale measures of current drug use. Latent variables of alcohol, marihuana, enhancer hard drugs, and dampener hard drugs were specified in a series of structural models. Contrary to previous findings with cumulative drug-use data, the common-factor model provided a more acceptable representation of the observed current-use data than did the simplex model in both samples. In addition, the similarity of results across both of these samples supports recent contentions by Huba and Bentler (1982) that quantitatively measured variables are not necessarily superior to qualitative, ordinal indicators in latent variable models of drug use.

Validity of self-reports of alcohol and other drug use: A multitrait-multimethod assessment.

Used 4 methods (self-reported rating, self-reported intake, peer-reported rating, and peer-reported intake) and multiple analytical criteria to assess the construct validity of reports of 3 types of substance use (alcohol, marihuana, and cigarettes) in a study of 194 college students who were members of friendship pairs. Ss answered questions about their own use and their friend's use of substances, classified their own and their friend's use of each substance according to 6 categories, and completed scales measuring the negative consequences of marihuana and alcohol. The resulting multitrait-multimethod matrix was analyzed in the traditional fashion as well as with confirmatory factor analysis. Convergent and discriminant validity for the 3 substance use traits were quite adequate, although the validity of the peer-reported intake measure of alcohol use may be considered inadequate according to some criteria. Results demonstrate the usefulness of multimethod assessment and confirmatory factor analysis for research on construct validity and for derivation of more accurate measures of drug use.

“Physician and patient communication training in primary care: Effects on participation and satisfaction”: Correction.

Reports an error in "Physician and patient communication training in primary care: Effects on participation and satisfaction" by Kelly B. Haskard, Summer L. Williams, M. Robin DiMatteo, Robert Rosenthal, Maysel Kemp White and Michael G. Goldstein (Health Psychology, 2008[Sep], Vol 27[5], 513-522). There was a typographical error in the text on page 521, in the first sentence of the first full paragraph. The corrected sentence is provided in the erratum.

Social Support and Patient Adherence to Medical Treatment: A Meta-Analysis.

In a review of the literature from 1948 to 2001, 122 studies were found that correlated structural or functional social support with patient adherence to medical regimens. Meta-analyses establish significant average r-effect sizes between adherence and practical, emotional, and unidimensional social support; family cohesiveness and conflict; marital status; and living arrangement of adults. Substantive and methodological variables moderate these effects. Practical support bears the highest correlation with adherence. Adherence is 1.74 times higher in patients from cohesive families and 1.53 times lower in patients from families in conflict. Marital status and living with another person (for adults) increase adherence modestly. A research agenda is recommended to further examine mediators of the relationship between social support and health. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Patient adherence to cancer control regimens: Scale development and initial validation.

Describes the development of a 38-item self-report Adherence Determinants Questionnaire (ADQ) to assess 7 elements of patients' adherence to medical treatment and prevention: (1) perceptions of interpersonal care, (2) beliefs about susceptibility to disease, (3) beliefs about severity of disease, (4) assessments of perceived utility of adhering (efficacy and benefits vs costs of adhering), (5) perceptions of subjective social norms for adhering, (6) intentions to adhere, and (7) perceptions of supports available for and absence of barriers to adherence. Past adherence and health value were also assessed. In 4 diverse field settings, intentions to adhere were most highly correlated with the perceived utility of adhering. Adherence (self-reported and objectively measured) was related most strongly to the presence of supports for and the absence of barriers to adherence.
