Therapeutic strategies described as effective for anxiety disorders include behavioral and cognitive-behavioral procedures of exposure and coping of aversive situations. However, considering that the behavioral pattern common in anxiety disorders is the phobic avoidance, the application of these strategies may difficult the adhesion or promote escape and avoidance of the therapeutic process. The Functional Analytic Psychotherapy is an alternative for dealing with these avoidance/escape behaviors and it can promote coping responses. This case report describes an analysis of the therapeutic relationship of a client with Panic Disorder and Agoraphobia. The intervention based on FAP was considered to help dealing with the avoidance behavior in the therapeutic process. Results show the efficacy of the procedures adopted and confirm the possibility of using FAP for improving the effectiveness of the empirically based psychotherapies.

AbstractThe belief that one is in a worse situation than similar others (Relative Deprivation) has been associated with involvement in a range of maladaptive escape behaviors, including excessive risk taking. Yet not everyone scoring high on measures of relative deprivation makes maladaptive choices. We hypothesized that hope may ameliorate the negative effects of relative deprivation. In two laboratory-based experiments using a novel risk-taking task (N = 101) we show that hope reduces risk-taking behavior in relatively deprived participants. A third study (N = 122) extended the moderating effect of hope on relative deprivation to real-world risk behavior; increased hope was associated with decreased likelihood of loss of control of one’s gambling behavior in relatively deprived individuals. Nurturing hope in relatively deprived populations may protect them against maladaptive behaviors with potential applications for harm reduction.
