EDEXCEL A LEVEL PSYCHOLOGY PAPER 2(application of psychology) MARK SCHEME JUNE 2023

Question Number Answer Mark 1(a) AO1 (1 mark) One mark for a definition of reliability in relation to classification systems. For example:  A classification system for mental health is reliable if there is consistent diagnosis of mental health between clinicians (1). Look for other reasonable marking points. (1) Question Number Answer Mark 1(b) AO1 (2 marks), AO3 (2 marks) One mark for identification of each reason (AO1). One mark for justification of each reason (AO3). For example:  Different classification systems such as DSM and ICD may diagnose different mental health for a person presenting with the same symptoms so they may lack concurrent validity (1), as shown by Cooper et al. (1972) where the same patient was diagnosed with schizophrenia twice in New York two times more than in London (1).  Classification systems cannot always accurately predict how effective treatments will be for a given disorder, so they may lack predictive validity (1) as shown by Kuyken et al. (2008) who found that 75% of his participants stopped taking anti-depressants and more relapsed compared to MCBT, so classification systems cannot predict who anti-depressants will work for (1). Look for other reasonable marking points. (4) 6 Question Number Answer Mark 2 (a) AO2 (1 mark) One mark for an identification of the dependent variable in relation to the scenario. For example:  The dependant variable was whether the patients said they had improved, stayed the same or deteriorated after eight weeks of therapy (1). Answers must relate to the scenario. Generic answers score 0 marks. Look for other reasonable marking points. (1) Question Number Answer Mark 2(b) AO2 (1 mark), AO3 (1 mark) One mark for identification of one weakness in relation to the scenario (AO2). One mark for justification of the weakness (AO3). For example:  Charles’s sample may be biased as only those patients who felt they were responding well to their face to face or online therapy may have contacted him (1), so Charles’s results may not be representative of all patients receiving face to face or online therapy, so there may be issues with generalising the results (1). Answers must relate to the scenario. Generic answers score 0 marks. Look for other reasonable marking points.
