Evaluating psychometric properties of the Cantonese integrated Digit-in-Noise Test: perhaps the 2-digit sequence can also be used for hearing screening.

Objective: This study developed and validated the Cantonese integrated Digit-in-Noise Test (iDIN) for speech-in-noise measurement and hearing screening.

Design: The development of the Cantonese iDIN followed the International Collegium of Rehabilitative Audiology guidelines. Its psychometric properties, including normative data, psychometric function, test-retest reliability, and criterion validity, were established.

The benefits of emotionally salient cues on event-based prospective memory in bipolar patients and schizophrenia patients.

Prospective memory (PM) refers to the ability to remember to carry out a delayed intention in the future. Evidence suggests that emotionally salient cues can enhance PM functions in healthy population, but whether the benefit exists in schizophrenia and bipolar patients remains unclear. This study aimed to examine and compare the potential enhancement effect of emotional PM cues in schizophrenia patients and bipolar patients.

Impaired olfactory identification and hedonic judgment in schizophrenia patients with prominent negative symptoms.

Evidence suggests that schizophrenia patients have olfactory dysfunctions, but the relationship between olfactory identification, hedonic judgement, and negative symptomatology remains unclear. Few studies have investigated whether co-activation of pleasant and unpleasant emotions are more prevalent in schizophrenia patients. Thirty schizophrenia outpatients with prominent negative symptoms (PNS), 30 outpatients without PNS, and 30 controls completed the University of Pennsylvania Smell Identification Test, and were asked to identify the odourants and to rate their emotions.
