Study design: To be included, studies had to investigate the association between communication factors (verbal factors, nonverbal factors, or interaction styles) and constructs of the therapeutic alliance (collaboration, affective bond, agreement, trust, or empathy),

measured during encounters between health mTOR inhibitor practitioners and patients. Settings and participants: To be included, studies had to investigate any interaction between patients and clinicians (eg, physicians, nurses, physiotherapists) in primary care or rehabilitation settings (Box 1). Studies on mental illness were excluded because the nature of care and consultation may demand different interactions. Longitudinal studies and cross-sectional studies Clinicians interacting with patients in primary care or rehabilitation settings Association between communication factors and patient satisfaction, including: satisfaction with the consultation; satisfaction with the treatment approach used by clinicians; or satisfaction with the clinical outcomes after treatment Verbal, nonverbal, and interaction style factors used by clinicians: Studies were eligible if they investigated, during an interaction between clinicians and patients, the association of any verbal, nonverbal, and/or interaction style factors used by clinicians with a satisfaction Ku-0059436 nmr outcome. Verbal factors consisted of speech content used

between clinicians and patients, eg, psychosocial talk, defined as statements of empathy, reassurance and information

involving aspects of social and psychological behaviour ( Hall et al 1994). Nonverbal factors were defined as communication behaviour without speech content, eg, facial expression, body movement, tone of voice and interaction physical distance ( Haskard et al 2009). Interaction styles incorporate aspects of both verbal and nonverbal factors and include features such as affective connection and openness to patients, sharing of control and negotiation of options ( Flocke et al 2002). There was no restriction to coding systems used by studies to from categorise: verbal, nonverbal, and/or interaction style factors, eg, Roter Interaction Analysis System and Bales Process Analysis System (Oths 1994, Smith et al 1981); method of observation, eg, observed encounters, videotapes or audiotapes; or coders, eg, neutral observers, clinicians or patients. Studies that included actors or simulated patients were excluded. Satisfaction with care: Studies were included if they investigated the association of verbal, nonverbal, and/or interaction style factors with at least one of the following patient satisfaction outcomes: 1. Satisfaction with the consultation; Satisfaction needed to be reported by patients and there was no restriction on the tools employed to rate it.
