  1. All 5-point Likert scale labeled 1 = fully disagree to 5 = fully agree; except item 7 where 1 = very little to 5 = very much
  2. Items hypothesized to capture S = structural and C=Cognitive Social Capital in a 2-factor model or B=Bonding, Br = Bridging and L = Linking Social Capital in a 3-factor model
