N=394 weeks of exchanges for therapists and N=475 weeks of exchanges for clients. Indices were calculated as the mean of therapists' and clients' ratings on constituent items. SEQ and ARM items could range from 1 to 7. Alpha=internal consistency measured by the coefficient alpha.
The means are from prior studies of the SEQ (Cummings et al16; Dill-Standiford et al.40; Kivlighan et al.41; Nocita and Stiles42; Reynolds et al.43; Stiles et al.6; Stiles et al.15; Stiles and Snow33; Tryon44) and ARM (Agnew-Davies et al.25; Stiles et al.45; Stiles et al.24).
The Bond and Partnership indexes were highly correlated with each other, so we combined them, yielding a single core alliance index (following Stiles et al.45), which had a higher internal consistency reliability than either one alone.
