Description of intervention(s) / exposure
Social Cognition Training (SCT):
SCT is an evidence based psychosocial intervention administered by Clinical Psychologists with expertise in social information processing deficits. Targeted treatment addresses four key areas of social cognitive impairement; emotion recognition, theory of mind, social knowledge and attribution bias. Intervention is comprised of various online training programs and group based activities. The 6 week treatment program is delivered weekly (2 x 1 hour sessions) in a small group format of 6-8 participants for a total of 12 sessions. Participants will also undergo treatment as usual (TAU), that is, continuing their standard routine clinical care (e.g., psychiatrist appointment).

Oxytocin (OT) Nasal Spray:
Research focused on the neurobiology of social cognition and behaviour highlights the central role of Oxytocin (OT). This neuropeptide is implicated in modulating peer recognition and social approach/avoidance in mammals. It also plays a critical role in the development of partner preference and social bonds.

Approved by the Therapeutic Goods Administration (TGA), OT is supplied by a registered compounding chemist and is matched with an identical placebo containing all ingredients except the active OT. Participants are assigned one pre-packed treatment containing identical active OT or placebo nasal spray according to the randomisation schedule developed by the chemist. OT or placebo is administered twice daily for the 6 weeks of social cognition training. We use a standard adult dose of OT that has been used in previous human studies, 24 International Units (IU; 1 puff per nostril with each puff containing 12 IU) twice daily. Moreover, participants undergoing SCT will be asked to administer an additional 24 IU dose of OT (or placebo) 10 minutes prior to the commencement of group.

Outcomes
Primary outcome [1] 286335 0
Change in Social Cognition
1. The Reading the Mind in the Eyes Test (RMET; Baron-Cohen et al. 2001)

The RMET consists of 36 images displaying the eye-region of human faces and depict various emotional expressions. RMET tests the inference of the internal state from subtle affective facial expression. The participant is asked to pick which of the four words best describes what the person in the photo is thinking or feeling. RMET yields a total score of correct answers. The RMET has been used widely in the research literature to demonstrate social cognitive deficits in patients with schizophrenia.
Timepoint [1] 286335 0
Conducted at three assessment time points; pre assessment (following referral and diagnostic interview), post assessment (within two weeks following completion of group) and 3-month follow up.
Primary outcome [2] 286369 0
Change in Social Function
1. The Social Functioning Scale (SFS; Birchwood et al. 1990)

The Social Functioning Scale (SFS) assesses the most relevant areas of social functioning for the support of patients with schizophrenia within the community. The purpose of the scale is to provide a detailed evaluation of both the strengths and weaknesses of each patient?s social functioning and to identify specific objectives of intervention. The SFS covers seven areas of social functioning: (1) Withdrawal; (2) Interpersonal behavior; (3) Prosocial activities; (4) Recreation; (5) Independence-Performance; (6) Independence-Competence; and (7) Employment/Occupation.

Change in Positive and Negative Symptom Severity
1. The Scale for the Assessment of Positive Symptoms (SAPS; Andreasen, 1984a)

The SAPS and SANS are hallmark assessment measures of positive and negative symptoms that characterize Schizophrenia. The SAPS is a 34-item scale used to rate the severity of four positive symptoms of schizophrenia: Hallucinations, Delusions, Bizarre Behavior, and Formal Thought Disorder. Each symptom cluster is evaluated on the basis of a global rating. Symptoms are rated on a 6-point scale ranging from zero, for "none," to 5 for "severe." The SANS includes items reflecting the severity of 19 specific negative symptoms regrouped into five symptom subscales: Affective Flattening, Alogia, Avolition-Apathy, Anhedonia-Asociality, and Attention deficit. Each subscale includes a global rating resulting in a total of 24 items.
