This questionnaire has sound psychometric properties and comprises five dimensions: problem focused coping, positive cognitive reframing, distraction strategies, avoidance strategies and support seeking strategies.
The FAD (Epstein et al, 1983) covers seven dimensions: Problem Solving; Communication; Role Allocation; Affective Responsiveness; Affective Involvement; Behaviour Control; a 12-item General Functioning scale (Epstein et al, 1983).
The PCQ has three dimensions: approach, problem-focused avoidance, and emotion-focused avoidance and eight subscales: information seeking, problem solving, seeking social support, positive self-statements, behavioral distraction, cognitive distraction, externalizing, and internalizing/catastrophizing.
This instrument was originally divided into five coping dimensions (problem focused, self-blaming, seeking social support, wishful thinking and avoidance), but when we performed a principal component analysis (varimax rotation), the scree plot indicated a three-factor solution with 26 items.
The extension of Apollonius' problem to three dimensions, namely, the problem of finding a fifth sphere that is tangent to four given spheres, can be solved by analogous methods.
25 items form five dimensions (emotional problems, behavioural problems, hyperactivity, peer relationship problems, pro-social behaviour).
The present contribution is restricted to two-dimensional problems of linear elasticity, but the extension to three dimensions and other problem classes is straightforward.
The SDQ is a short questionnaire with 25 items and contains five dimensions: Emotional Problems, Conduct Problems, Hyperactivity/inattention, Peer Problems, and Prosocial Behavior (not used here).
Also, three dimensions of cooperation (problem solving, willingness to adapt to changes and restraint from use of power) were found to be directly associated with relationship performance while information sharing had indirect relationship with performance.
However, generic GFTs in three dimensions have the problem that the gluings are too arbitrary, in the sense that the generated simplicial complexes are not even pseudo-manifolds since they present wrapping singularities [7].
