Reward dependence
In psychology, reward dependence (RD) is a personality trait. It can be assessed within the Tridimensional Personality Questionnaire (TPQ) personality test where it is one of the resulting dimensions alongside "harm avoidance" and "novelty seeking". It is also found in the newer version of the personality test called Temperament and Character Inventory (TCI) and its revised version (TCI-R).
The so-called subscales of reward dependence in TCI-R are
- Sentimentality (RD1)
- Openness to warm communication (RD2)
- Attachment (RD3)
- Dependence (RD4)
C. Robert Cloninger, that devised the TPQ and TCI questionnaires, suggested that RD is correlated with low noradrenergic activity.[1] This suggestion has led to research that, e.g., investigates whether genes of the noradrenaline system are associated with variation in reward dependence. As an example: One study looked for the effect from a genetic variant, C-182T (rs2242446), in the norepinephrine transporter gene.[2]
