1 2 Positive Emotion Specificity and Mood Symptoms 3 in an Adolescent Outpatient Sample 4

8 Abstract Research on positive emotion disturbance has 9 gained increasing attention, yet it is not clear which 10 specific positive emotions are affected by mood symptoms, 11 particularly during the critical period of adolescence. This 12 is especially pertinent for identifying potential endophe13 notypic markers associated with mood disorder onset and 14 course. The present study examined self-reported discrete 15 positive and negative emotions in association with clini16 cian-rated manic and depressive mood symptoms in a 17 clinically and demographically diverse group of 401 out18 patient adolescents between 11 and 18 years of age. 19 Results indicated that higher self reported joy and contempt 20 were associated with increased symptoms of mania, after 21 controlling for symptoms of depression. Low levels of joy 22 and high sadness uniquely predicted symptoms of depres23 sion, after controlling for symptoms of mania. Results were 24 independent of age, ethnicity, gender and bipolar diagnosis. 25 These findings extend work on specific emotions impli26 cated in mood pathology in adulthood, and provide insights 27 into associations between emotions associated with goal 28 driven behavior with manic and depressive mood symptom 29 severity in adolescence. In particular, joy was the only 30 emotion associated with both depressive and manic 31 symptoms across adolescent psychopathology, highlighting 32 the importance of understanding positive emotion distur33 bance during adolescent development. 4
