Sentences with phrase «emotionality scores»

Correlation analysis between scores in negative emotionality and history of marijuana abuse showed a negative correlation between age of initiation of marijuana abuse and negative emotionality scores (r = 0.58, P = 0.003) such that the younger the initiation, the higher the scores.

Not exact matches

In ventral striatum (key brain reward region), MP - induced reductions in DVs and BPND (reflecting DA increases) were inversely correlated with scores of negative emotionality, which were significantly higher for marijuana abusers than controls.

Marijuana abusers showed lower scores on positive emotionality and higher scores on negative emotionality than controls, consistent, on the one hand, with lower reward sensitivity and motivation and, on the other hand, with increased stress reactivity and irritability.

However, the groups differed significantly in personality measures; marijuana abusers had significantly lower scores in positive emotionality (P = 0.05) and higher scores in negative emotionality (P = 0.002) than controls (Table 1).

(B) SPM results for the voxel-wise correlation between MP - induced decreases in BPND (ΔBPND) and scores in negative emotionality (NEM).

Demographics, clinical characteristics, and personality scores (positive emotionality, negative emotionality, and constraint) of participants, and the significance for the comparisons between healthy controls and marijuana abusers

We predicted that MP's behavioral effects in marijuana abusers would be attenuated, consistent with preclinical findings (30), and that decreased DA reactivity in ventral striatum would be associated with higher scores in negative emotionality (neuroticism), which mediates genetic risk for marijuana dependence (31), and with addiction severity.

Positive emotionality is a combination of scores for well - being (reward sensitivity), social potency, achievement (motivation), and social closeness; negative emotionality is a combination of scores for stress reaction, alienation, and aggression; and constraint is a combination of scores for self - control, harm avoidance, and traditionalism.

Because the SPM revealed a significant group difference in MP - induced changes in midbrain BPND, we also performed correlations with this brain region and showed a significant correlation with positive emotionality (r = 0.42, P = 0.003) such that the greater the BPND decreases, the lower the scores.

The emotionality items and the framing items were summed to create separate composite indices, with higher scores reflecting a greater degree of agreement that messages were perceived as intended.

Children diagnosed as Combined or Predominantly Hyperactive Impulsive Type had significantly higher scores than those diagnosed as Predominantly Inattentive Type in anxious and avoidant attachment, emotionality, and activity dimensions of temperament, and their parents reported higher levels of controlling styles.

A summary score of coparental conflict measured when children were 4, 8, and 12 month - old explained unique variance in toddler behavioral inhibition at 30 months (r =.38, p <.05), above the effects of infant negative emotionality at 4 months.

At age 5, eight temperamental characteristics were assessed: negative emotionality, inhibition, activity level, task persistence (scored in nonpersistent direction), biological irregularity, emotional intensity, stimulation threshold, the tendency to be slow to adapt to change and mood.
