  • Mumford & Whitehouse (1988)
    • Sample
      • The sample used was large (559 - 204 white, 355 Asian) which increases generalisability and reliability of data.
      • Sample was aged 14-16 which is limited and cannot be generalised to older women or girls younger than 14.
      • The sample was taken from Bradford schools. This is a metropolitan area and is therefore representative of the UK.
    • Research Methods
      • Questionnaires gathered primary data which could be biased due to the experimenters interpretation of the data.
        • Untitled
      • Primary data increases the validity of the study as it relates directly to the aim - if prevalence of ED's is fewer in British Asians school girls than white counterparts.
      • Only 75% attended the interviews which decreases reliability and validity as it could have been a biased sample.
      • Self report data was gathered on honesty and social desirability bias which is open to interpretation and
    • Researchers
      • Both researchers were male - could be subjected to gender bias
        • Male researchers could influence the girls' answers as they may not want to admit their feelings to a male.
    • Diagnosis of ED
      • The diagnosis' were made using DSM III - R. Nicholls et al (2000) said this was not a reliable measure of ED in children.
      • The decision was a joint decision amongst more than one researcher which increases inter - rater reliability.
        • Joint decision also increases criterion validity as different researchers use to the same DSM to make the diagnosis.
