“…On the one hand, there is evidence for a linear trend of alliance development displaying a consistent strengthening of the alliance over the course of treatment (e.g., Fitzpatrick, Iwakabe, & Stalikas, ; Rubel, Lutz, & Schulte, ; Sauer, Lopez, & Gormley, ). On the other hand, some studies describe a nonlinear U‐shaped trend or rupture‐resolution processes (e.g., Gelso & Carter, ; Horvath & Luborsky, ; Kivlighan Jr, Kline, Gelso, & Hill, ; Rubel, Bar‐Kalifa, et al, ; Safran & Muran, ). Both patterns of alliance development have received attention and lend support to the impact of the selection of the time point of assessment during treatment and the consideration of individual differences in alliance development.…”
