Detailed explanation-1: -Meehl believed that schizophrenia is the result of a single schizogene, combined with chronic stress, in particular the schizophrenic mother. Meehl believed that if a person did not have the schizogene, then no amount of stress would lead to schizophrenia.
Detailed explanation-2: -Interactionist approaches attempt to explain schizophrenia as a combination of nature (biological) and nurture (environmental) factors. Diathesis-stress model: Meehl (1962) originally proposed that both a vulnerability to schizophrenia and a stress-trigger are necessary in order to develop the condition.
Detailed explanation-3: -The neural diathesis–stress model of schizophrenia proposes that stress, through its effects on cortisol production, acts upon a preexisting vulnerability to trigger and/or worsen the symptoms of schizophrenia.
Detailed explanation-4: -An interactionist approach argues that several levels of explanation are necessary to explain a particular behaviour, ranging from lower (biological) to higher levels (social and cultural).
