Summary of Research Findings

The dynamics of character strengths remains a new area of study. One model for looking at the dimensionality of character strengths is to place each strength on a continuum in which too much of a strength in a particular context becomes overuse, too little is underuse, and the center area is the “strengths zone” or optimal expression (i.e., golden mean) of the strength.

  • Discusses the phenomenon of extreme social withdrawal in large numbers of Japanese youth, known as hikikomori, using the lens of character strengths overuse, underuse, and optimal use within case examples (Matsuguma & Niemiec, 2020).

  • Reviews philosophical theories on the golden mean concluding that the relationship between virtue and behavior is addressing situation-specific optimality; challenges traditional measurement approaches and explains why virtues cannot be accurately measured as general tendencies in behavior (Ng & Tay, 2020).

  • Offers central arguments, concepts, and theory for the existence of character strengths overuse, underuse, and optimal use. Tables for overuse, underuse, optimal use, and top correlates across the 24 strengths are provided. Suggests practical strategies for researchers, based in theory, to test and for practitioners to experiment with, such as the tempering effect, the towing effect, strengths-spotting, direct questioning, feedback, and mindfulness (Niemiec, 2019).

  • Second ever empirical study examining the overuse, underuse, and optimal use across 24 character strengths, replicating the previous findings that overuse and underuse are each significantly associated with less flourishing and life satisfaction and greater depression while optimal use is significantly associated with the reverse of these three outcomes. The study also found that the following pattern could correctly sort (with 89.3% accuracy) whether someone has clinical levels of obsessive-compulsive disorder (OCD) or not: overuse of social intelligence, judgment, appreciation of beauty/excellence, fairness, prudence and underuse of forgiveness and self-regulation (Littman-Ovadia & Freidlin, 2019).

  • Study of 100 people on health and overuse, underuse, and optimal use of character strengths. The study replicated previous findings around the benefits of optimal strengths use and the negative impact of strengths overuse and underuse. Optimal character strengths use predicted better physical and mental health, and more frequent health behaviors and positive emotions. Underuse predicted each of these in the opposite direction as optimal use. The same was true of overuse with the exception of overuse not predicting worse mental health. In all cases, as in previous studies, the underuse of character strengths was more negatively impactful, but with one exception – overuse was worse than underuse for physical health (Bergen, 2019).

  • Pilot study of 79 students finding that underuse of character strengths related to poor academic performance while optimal use related to good academic performance (strengths overuse had a positive, nonsignificant correlation). More specifically, the optimal use of perseverance, love of learning, and self-regulation accounted for 68% of the variance in academic performance (Powell, 2018).

  • The first empirical study to examine overuse, underuse, and optimal-use of character strengths. Several findings: First, it reveals that these constructs do indeed exist for the 24 character strengths; second, overuse and underuse were significantly related to higher depression, less flourishing, and less life satisfaction (with underuse of character strengths doing worse) while the optimal-use (i.e., golden mean) of character strengths was significantly related to higher flourishing and life satisfaction and less depression; third, 87.5% of individuals with or without a clinical diagnosis of social anxiety disorder (social phobia) were able to be correctly sorted to having or not having the condition based on a combination of several overuses and underuses of character strengths. Finally, the study introduces a new research assessment measure called Overuse, Underuse, Optimal-Use (OUOU) of Character Strengths (Freidlin, Littman-Ovadia, & Niemiec, 2017). The instrument is available free to researchers on the VIA site.

  • Seligman (2015) champions the work of Peterson (2006) who began to explore the connection between each of the 24 character strengths and differing types of psychopathology. Peterson framed each of the 24 around excess, absence, and opposite of the strength. This model was then made more practical and consistent with “golden mean” methodology of strengths use dating back to Aristotle by describing each character strength in terms of a continuum of overuse and underuse where optimal-use lies in the center (Niemiec, 2014). The first empirical study with psychopathology was then published examining this revised framework in individuals with social anxiety disorder (Freidlin et al., 2017).
