Look at gardening it is a good form of therapy and one which a lot of mental health organisations promote. Working with soil is very therapeutic and relaxing and something which could be used in tandem with medication. If you look for books and journals around gardening and mental health you might find more information

One of the best resources is the National Institutes of Mental Health, which has a nice summary of treatment methods and other resources at

Background: Psychological interventions are increasingly recommended as adjunctive treatments for psychosis, but their implementation in clinical practice is still insufficient. The individualized metacognitive therapy program (MCT+; www.uke.de/mct_plus ) represents a low-threshold psychotherapeutic approach that synthesizes group metacognitive training (MCT) and cognitive behavioral therapy for psychosis, and addresses specific cognitive biases that are involved in the onset and maintenance of psychosis. It aims to “plant the seed of doubt” regarding rigid delusional convictions and to encourage patients to critically reflect, extend and change their approach to problem solving. Its second edition also puts more emphasis on affective symptoms. A recent meta-analysis of metacognitive interventions (MCT, MCT+) indicate small to moderate effects on positive symptoms and delusions, as well as high rates of acceptance. Nonetheless, no long-term studies of MCT+ involving large samples have been conducted. Methods: The goal of the present multi-center, observer-blind, parallel-group, randomized controlled trial is to compare the efficacy of MCT+ against an active control (cognitive remediation; MyBrainTraining©) in 328 patients with psychosis at three time points (baseline, immediately after intervention [6 weeks] and 6 months later). The primary outcome is change in psychosis symptoms over the 6-month follow-up period as assessed by the delusion subscale of the Psychotic Symptom Rating Scale. Secondary outcomes include jumping to conclusions, other positive symptoms of schizophrenia, depressive symptoms, self-esteem, quality of life, and cognitive insight. The study also seeks to elucidate mediating factors that promote versus impede symptom improvement across time. Discussion: This is the first multi-center randomized controlled trial to test the efficacy of individualized MCT+ in a large sample of patients with psychosis. The rationale for the trial, the design, and the strengths and limitations of the study are discussed.Trial Registration: (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Clinicians and patients differ concerning the goals of treatment. Eighty individuals with schizophrenia were assessed online about which symptoms they consider the most important for treatment, as well as their experience with different interventions. Treatment of affective and neuropsychological problems was judged as more important than treatment of positive symptoms (p < 0.005). While most individuals had experience with Occupational and Sports Therapy, only a minority had received Cognitive-Behavioral Therapy, Family Therapy, and Psychoeducation with family members before. Patients appraised Talk, Psychoanalytic, and Art Therapy as well as Metacognitive Training as the most helpful treatments. Clinicians should carefully take into consideration patients’ preferences, as neglect of consumers’ views may compromise outcome and adherence to treatment.

Forming a trusting alliance with your patient needs to come first and listening to his/her perspective and what needs changing from their point of view is an excellent way to start. Many patients who are described as paranoid are very frightened - addressing that fright needs to be done before anything else. Some patients will want a close family member involved in treatment decisions, and some will not. That needs to be respected. Discuss treatment options with the patient and see what way they are leaning. Some may want a second opinion. Each person is different.

There is a fair amount of evidence suggesting that cognitive-behavioral therapy, while certainly not a cure for schizophrenia nor a substitute for antipsychotic medications, can help manage its symptoms and improve psychosocial functioning. These treatments vary, but can include cognitive restructuring, social skill training, and social cognition training.

Some evidence also suggests that cognitive remediation can be helpful, particularly for some of the negative symptoms and cognitive impairments seen in patients with schizophrenia.  Some of these programs involve exercises designed to improve cognitive function, whereas others teach compensatory strategies to help the person function better despite the presence of cognitive impairments.
