The aim of this thesis is to study (1) the impact of physicians' locus of control (LOC) on their communication styles in interviews with cancer patients as well as (1) the impact of physicians' LOC on their acquisition of effective communication skills in a communication skills training program. LOC is a generalised belief regarding the extent to which life outcomes are controlled by an individual's actions (“internal” LOC) or by external forces such as luck, fate or other individuals (“external” LOC). (1) Although is it widely recognised that physicians' characteristics could influence their communication styles and may thus interfere with a patient-centred communication, no empirical evidence is currently available. No studies are available on the impact of physicians' LOC on their communication skills. It was hypothesised that physicians with an “external” LOC have a different communication style than physicians with an “internal” LOC. Eighty-one voluntary physicians with a practice in oncology were recorded performing an actual and a simulated interview with a cancer patient as wall as an actual and a simulated interview with a cancer patient and a relative. Physicians' communication skills were assessed using the Cancer Research Campaign Workshop Evaluation Manual. Physicians' LOC was assessed using the Rotter I-E scale. Communication skills of the upper and lower quartiles of physicians in respect of their scores on this scale were compared using Student's t-test. Results show that physicians with “external” LOC give more appropriate information than physicians with “internal” LOC in simulated interviews with a cancer patient (P=0.011) and less premature information than physicians with “internal” LOC in clinical interviews with a cancer patient (P=0.015). Moreover, in actual interviews with a cancer patient and a relative, physicians with an “external” LOC talked more to the relative (P=0.017) and used more utterances with an assessment function (P=0.010) than physicians with an “internal” LOC. In simulated interviews with a cancer patient and a relative, physicians with an “external” LOC used less utterances giving premature information (P=0.031) and used more utterances with a supportive function such as empathy and reassurance (P=0.029) than physicians with an “internal” LOC. (2) Although it is widely recognised that educational interventions may be more effective for people with an “internal” LOC compared to people with an “external” LOC, no study has yet assessed the influence of physicians' LOC on communication skills learning. This study aims to test the hypothesis that, in a communication skills training program, physicians with an “internal” LOC would demonstrate communication skills acquisition to a greater degree than those with an “external” LOC. A non-randomised longitudinal intervention study was conducted between January 1999 and April 2001. Sixty-seven volunteer physicians from private and institutional practice in Belgium participated to a learner-centred, skills-focused, practice-oriented communication skills training program. Communication skills changes were assessed in 2 standardised simulated interviews before and after training (one two-person and one three-person interview). Communication skills were assessed using the Cancer Research Campaign Workshop Evaluation Manual. Physicians' LOC was assessed using the Rotter I-E scale. Communication skills changes of the upper and lower third of physicians in respect of their scores on this scale were compared using group by time repeated measures of variance. In the two-person and three-person interviews, the increase in open directive questions was more important among physicians with an “internal” LOC compared to physicians with an “external” LOC (P=0.066 and P=0.004 respectively). In the three-person interview, the increase in directive questions (P=0.001), in assessing functions (P=0.002) and in the use of moderate feelings stated explicitly (P=0.011) was more important among physicians with an “internal” LOC compared to physicians with an “external” LOC. Conclusion. These results provide evidence that physicians' LOC can influence their communication styles as well as the efficacy of a communication skills training program. Physicians' awareness of first results constitutes a step towards a tailoring of their communication skills to every patient's and relative's concerns and needs and thus towards a patient-centred communication. The second results support the idea that a psychological characteristic such as "internal" LOC may facilitate communication skills acquisition through physicians' belief that communication with patients may be controlled by physicians themselves.

[Truncated abstract] This PhD project was comprised of three major studies. Study 1 utilised the Nominal Group Technique (NGT) to identify a typology of difficult patients in private practice physiotherapy and to determine strategies physiotherapists use and would like to improve, when dealing with such patients. Physiotherapists (n=37) also shared their expectations of patients and their perceptions of patient expectations of physiotherapy. Results showed that the two areas most difficult to manage were behavioural problems of patients followed by patient expectations. To assist in their interaction with difficult patients, physiotherapists identified communication skills and behaviour modification techniques as strategies they would most like to learn. While physiotherapists expressed the greatest number of expectations in the behavioural domain, identification of patient expectations was not elicited as a strategy to manage difficult patients. Results of this qualitative study contribute to the evolving literature relating to physiotherapist-patient interactions and form a useful basis for educational programs directed at improving the therapeutic relationship in private practice physiotherapy. Study 2 involved applying the NGT with separate groups of patients (n=26) to identify patient expectations of the qualities of a ‘good’ physiotherapist, and to ascertain the characteristics of good and bad experiences in private practice physiotherapy. Findings indicated that the qualities of a ‘good’ physiotherapist related to their communication ability, professional behaviour and organisational ability, and characteristics of the service provided. The most important expectations of patients were for example, symptomatic relief, self-management strategies and ‘hands on’ treatment; associated with the physical domain. When comparing equivalent groups from Study 1, with patient expectations, most patient groups identified that the most important expectations of physiotherapists would relate to patient behaviours such as; compliance, honesty, payment of their account, being punctual, cooperating, trusting and showing respect for their physiotherapist. However, physiotherapists’ rankings of the most important expectations held by patients were not congruent with patient rankings providing an explanation as to why problems may arise in the physiotherapistpatient interaction from the patient’s perspective. Based on the findings of Study 2 it was suggested that physiotherapists should actively seek to involve patients in their management. To do this effectively, physiotherapists would benefit from further training in communication skills to ensure that they can successfully adopt a patientcentred approach and to optimise the physiotherapist-patient interaction in private practice physiotherapy.

Effective doctor-patient communication is critical to improving health outcomes. Good communication improves emotional health, symptom resolution, functional and physiologic status, and pain control. Conversely, ineffective communication leads to misdiagnosis, inappropriate treatment poor adherence, misuse of health services, and high patient stress. In the U.S., Hispanics are the fastest growing minority. Despite the high burden of illness among this population, Hispanics are less likely than other minorities to regularly see a health professional. This is explained in part because Hispanics navigate a health system designed for the majority, experience a mismatch between cultural values and health beliefs, and have limited English proficiency. These communication challenges contribute to health disparities among the Hispanic population living in the U.S. Despite the importance of doctor-patient communication, few communication interventions that focus on improving patient skills have been tested in this population. Therefore, the purpose of this study was to evaluate whether a patient communication intervention tailored for female Hispanic patients could be practically implemented in a practice setting. The first aim focused on adapting existing communication skills training tools for a Hispanic population. The second aim assessed the feasibility of implementing the training tool in a federally qualified health center in a US-Mexico border community. The third aim explored the extent to which trained patients were able to integrate the information provided. Results indicate that it is feasible to implement communication training when delivered by clinical staff. Patient follow-up revealed that patients valued training on how to communicate with their doctor the most. Moreover, it is feasible to sustain the intervention when it is aligned with the priorities of the clinical site. Patient communication training in medically underserved rural areas could improve barriers to improved health outcomes in communities with a high prevalence of Hispanic patients. Future funding is needed to further test, dissemination of communication training programs.

Objective This study tested the effectiveness of a brief, learner-centered, breaking bad news (BBN) communication skills training module using objective evaluation measures. Methods This randomized control study (N = 66) compared intervention and control groups of students (n = 28) and residents’ (n = 38) objective structured clinical examination (OSCE) performance of communication skills using Common Ground Assessment and Breaking Bad News measures. Results Follow-up performance scores of intervention group students improved significantly regarding BBN (colon cancer (CC), p = 0.007, r = −0.47; breast cancer (BC), p = 0.003, r = −0.53), attention to patient responses after BBN (CC, p < 0.001, r = −0.74; BC, p = 0.001, r = −0.65), and addressing feelings (BC, p = 0.006, r = −0.48). At CC follow-up assessment, performance scores of intervention group residents improved significantly regarding BBN (p=0.004, r = −0.43), communication related to emotions (p = 0.034, r = −0.30), determining patient's readiness to proceed after BBN and communication preferences (p = 0.041, r = −0.28), active listening (p = 0.011, r = −0.37), addressing feelings (p < 0.001, r = −0.65), and global interview performance (p = 0.001, r = −0.51). Conclusion This brief BBN training module is an effective method of improving BBN communication skills among medical students and residents. Practice implications Implementation of this brief individualized training module within health education programs could lead to improved communication skills and patient care.
