“…This has led to a growing number of investigations on positive emotions (Fredrickson & Joiner, ) and subjective well‐being (Diener, ; Diener et al, ), human strengths (Peterson & Seligman, ) and other positive personality characteristics such as compassion, hope and altruism (Park et al, ). These positive issues have been used as specific ingredients in so‐called ‘positive interventions’ (Magayar‐Moe, ; Rashid, ; Seligman et al, ; Sin & Lyubomirsky, ), which have been recently proposed: positive psychotherapy (Seligman et al, ), wisdom psychotherapy (Linden et al, ), gratitude interventions (Wood et al, ), positive coaching (Biswas‐Diener, , ), strengths‐based approaches (Biswas‐Diener et al, ; Govindji & Linley, ; Linley & Burns, ), hope therapy (Geraghty et al, ; Snyder et al, ) and forgiveness therapy (Lamb, ). All these new interventions that share a common theoretical background have not been sufficiently tested in clinical populations.…”
