Abstract Introduction Light emitted from visual displays can acutely increase alertness, improve cognitive performance and suppress melatonin in the evening. Here we tested the influence of different melanopic irradiance levels emitted by a metameric display setting on alertness, vigilance and salivary melatonin levels. Methods In an ongoing study, 37 healthy, male participants have so far completed a 2-week study protocol. Volunteers were assigned to one of four luminance groups which differed in brightness levels (27 cd/m2 - 280 cd/m2). Illuminance ranged between 7 and 85 lx. Within the four groups each volunteer was exposed to a low melanopic (LM) and a high melanopic condition (HM). The LM and HM differed in melanopic irradiance (ca. 3-fold change), but matched in terms of cone excitation (metamers). Before, during and after the light exposure, volunteers performed a psychomotor vigilance task (PVT). Subjective alertness and melatonin levels were continuously measured in half-hourly intervals throughout scheduled wakefulness in the 17-h in lab study. Results Preliminary analysis yielded an overall alerting response in the HM vs. the LM condition (p<0.05) concomitant with a trend of reduced melatonin levels in HM vs. LM (p=0.08). So far, we could not observe a difference in PVT performance for HM and LM (Reaction time responses between 100 and 500 ms). Since we are still lacking statistical power in the ongoing study, we cannot yet satisfactorily interpret interaction effects between melanopic condition and brightness. Conclusion Our data indicate that rather low brightness levels of high melanopic display light impacts alertness and melatonin levels in the evening. Thus, metameric low melanopic display light may be a promising method to attenuate activating properties of evening light on circadian physiology without affecting visual appearance.

AbstractBackground:Therapist validation in treatment is theorized to be related to positive outcomes (Linehan, 1993), including keeping patients in therapy longer.Aims:We sought to evaluate the role of therapist validation from both therapists’ and clients’ perspectives as a predictor of drop-out from psychotherapy in three cognitive behavioural training clinics.Method:Clients in psychotherapy (n = 50; 80% female; 82% Caucasian) and their trainee therapists (n = 22; 68% female; 86% Caucasian) rated validation by the therapist at each of four early sessions of therapy.Results:After accounting for symptom severity, clients who reported greater therapist validation were less likely to drop out of treatment. Therapist ratings of their own validating behaviours were unrelated to client drop-out. Therapist experience moderated the relation between client-rated validation and drop-out, such that validation was unrelated to drop-out for more experienced therapists.Conclusions:Assessing and attending to client perceptions of validation by the therapist early in treatment, with brief self-report inventories, can alert therapists to clients at greater risk of drop-out.
