“…The quantitative elements of the mixed methods approaches included surveys [ 16 ], network analysis [ 19 ] and hypothesis testing using Pearson Chi-Square tests [ 23 ]. Among the qualitative and mixed method approaches, a case study design was frequently adopted [ 16 – 18 , 20 , 21 , 23 , 26 , 27 , 31 ], with interviews (typically semi-structured) being the most commonly used method [ 15 , 17 , 18 , 25 , 27 , 29 , 31 ]. However, these similar approaches were selected from differing theoretical frameworks, such as the absorptive capacity framework [ 27 ], a communications perspective [ 19 ], a more contextual Theory-based Impact Evaluation [ 17 , 18 ], and the Identity-Legitimacy-Life Cycle (ILLC) model [ 26 ].…”
