Intercultural communication competence in family medicine: lessons from the field.

OBJECTIVE: To describe the challenges for immigrant patients and their physicians and their skills in intercultural communication (ICC). METHODS: We videotaped one clinical encounter for each of 24 psychologically distressed patients visiting their regular family physician. The physician and the patient, each separately, viewed the videotape of their clinical encounter and commented on important moments identified by the participant or the researchers. RESULTS: Patients and/or physicians lacked knowledge of the effects of culture on the doctor-patient relationship and expressions of distress as well as the effects of immigrant-specific stress on health. Most subjects were motivated to have an interpersonal, rather than an intercultural encounter. Physicians and patients demonstrated the skills needed to achieve an interpersonal encounter. Some physicians and their patients achieved intercultural meetings as a result of their interpersonal interactions over a period of years. DISCUSSION: Lack of formal training partly explains why most participants demonstrated an elementary level of ICC. In addition, Identity Management Theory and Co-cultural Theory explain some of the barriers to ICC. PRACTICE IMPLICATIONS: Providing physicians with formal training in intercultural communication and empowerment training for patients is likely to improve the quality of care of immigrants.

Toward energy harvesting using active materials and conversion improvement by nonlinear processing.

This paper presents a new technique of electrical energy generation using mechanically excited piezoelectric materials and a nonlinear process. This technique, called synchronized switch harvesting (SSH), is derived from the synchronized switch damping (SSD), which is a nonlinear technique previously developed to address the problem of vibration damping on mechanical structures. This technique results in a significant increase of the electromechanical conversion capability of piezoelectric materials. Comparatively with standard technique, the electrical harvested power may be increased above 900%. The performance of the nonlinear processing is demonstrated on structures excited at their resonance frequency as well as out of resonance.

GHQ-28 and cGHQ-28: implications of two scoring methods for the GHQ in a primary care setting.

BACKGROUND: The General Health Questionnaire allows for distinguishing patients suffering from psychiatric problems from those in good mental health. There is some controversy as to the best scoring method. Two different methods have been proposed: GHQ and cGHQ. The present study aims at verifying whether there is confirmation of the hypothesis that the population resulting from the cGHQ calculation presents greater chronicity. METHOD: A total of 40 general practitioners and 1145 of their patients in the Greater Montreal area, Québec, Canada participated in the original study. A sub-group of 313 patients were followed over a 3-month period. The patients were asked to complete a set of questionnaires, including the GHQ-28. The traditional method of calculating the GHQ score and the alternative cGHQ method were used. RESULTS: Two discordant groups of patients were identified: Group 1 (acute cases only), positive on the GHQ, but negative on the cGHQ (n = 124), and Group 2 (chronic cases only), negative on the GHQ and positive on the cGHQ (n = 64). Patients in Group 2 were older (p<0.001), were more worried about their health (p = 0.06) and their health problem had lasted for a longer time (p = 0.02). Patients in Group 2 were twice as likely to remain positive on the GHQ and/or the cGHQ as those in Group 1 in the 1- and 3-month follow-ups. CONCLUSIONS: The results suggest the presence of notable differences between the two groups, generally explainable by the hypothesis of greater chronicity in the cGHQ patients. The results confirm the impact of the choice of calculation method on the composition of the two groups. Finally, the authors suggest using the two calculation methods simultaneously.
