Affectometer 2 is a 5-minute inventory of general happiness or sense of well-being based on measuring the balance of positive and negative feelings in recent experience. Since this scale is directly derived from its parent scale, Affectometer 1, psychometric findings on the longer scale are reported along with initial data on Affectometer 2 . These results indicate high reliability, high validity, and slight contamination by current mood and social desirability. Among the findings of special interest are: (a) the independence of positive and negative affect proposed by Bradburn is not confirmed; (b) well-being is highly and inversely related to neuroticism, anxiety, depression and somatic complaints; (c) the relationship of well-being to depression is curvilinear; (d) well-being scores are determined more by short-term states than long-term traits; (e) well-being can be characterized by 10 "qualities of happiness".' The curve shown in Figure 1 is also supported by other recent data. Using Affectometer 1, A.G. Cramb and M. D. Hills observed a 15-week test re-test r of 072 on a sample of 45 adults, close to the predicted r of 066. Several other well-being scales used with a random sample of 3288 Canadians, have yielded 2-year test-retest rs in the ranges -40 to -53 as reported by Atkinson (1982).

Post-MTBI fatigue is a persistent post-concussion symptom, exacerbated by depression but not anxiety. It diminishes in the first 3 months and then becomes relatively stable, suggesting the optimum intervention placement is at 3 months or more post-MTBI.

The Patient Competency Rating Scale (PCRS) provides self- and informant-ratings of everyday memory and gives a guide to patients' awareness of their difficulties. Research using the PCRS has focussed on groups with severe TBI and little is known about ratings of functioning in other severity groups or in a non-TBI population. In the current study the TBI group (n = 53) overrated their pre-accident competency compared to controls (n = 131). Patients with severe TBI (n = 25) underestimated their difficulties, while ratings of those with moderate (n = 14) and mild (n = 14) TBI were consistent with their informants, that is, in areas of cognition and emotion. Controls reported difficulty in interpersonal functioning and emotional control that their informants were unaware of.

The CUPIT is a brief cannabis screener that is reliable, valid and acceptable for use across diverse community settings and consumers of all ages. The CUPIT has clear potential to assist with achievement of public health goals to reduce cannabis-related harms in the community.
