9 KEY FEATURES: Self-Report
Self-report is a method of data collection in which the participant themselves answer questions about their behaviour, thoughts and feelings. Questions may be asked in an interview or in the form of a questionnaire that participants are asked to respond to. Instead of using an objective method of data collection, participants are asked to make subjective judgements. Interviews are ac commonly used technique in clinical psychology and psychotherapy. They can be structured, semi structured or unstructured. Usually self-report questions are responded to by participants themselves, although occasionally others respond for them e.g. In the case of small children or people with learning difficulties who are unable to respond on their own behalf. The most common form of self-report in psychological investigations is the questionnaire or psychological measure. As with observations, self-report is a method in its own right, but it is also frequently incorporated into experiments

13 Method of Self Report: Questionnaires

14 KEY FEATURES: Questionnaires
Questionnaires and psychological tests such as personality test and IQ tests are all self-report measures. Questions in a questionnaire can be open or closed. Open questions area open ended and allow free rein in answering them. Closed questions have a limited number of possible responses. They can be questions that require a simple yes/no answer or they require an answer from a range of possible answers. Questionnaires frequently use rating scale. They can consist of questions ore statements that participants respond to on a scale (e.g. Likert scale) where responses may take the form of ‘strongly disagree’ to ‘strongly agree’ on a scale of 1-4 where 1=strong disagree and 4=strongly agree. If participants have to select answers from a range of possible responses they can be referred to as forced-choice questions.

15 OVERVIEW: Questionnaires
Nature & Use Set of questions Design: open (qual) or closed (quan) Advantages A lot of data can be collected Does not require specialist administrators People are more willing to answer embarrassing or personal questions on an anonymous written questionnaire than in a face-to-face interview Disadvantages Leading questions, social desirability bias Biased samples Ethical Issues Confidentiality Privacy

16 Method of Self Report: interview

17 Unstructured - Structured - Semi Structured
KEY FEATURES: Interviews Unstructured - Structured - Semi Structured Unstructured interview In an unstructured interview there is no predetermined structure in the interview, although the interviewer will normally have some goal or sense of direction in mind. The interviewer will ask open-ended questions and the answers given by the interviewee stimulate new questions. The directed but unstructured interview is the type of interview normally used in a therapeutic context as a therapist’s aim will enable the patient to talk. Structured interview In a structured interview the interviewer has a predetermined list of questions which they stick to. Respondents are all asked the same questions in the same order. Semi-Structured interview In a semi-structured interview the interviewer has a list of questions but the approach is flexible and can be shaped by the interviewee’s responses.

18 OVERVIEW: Interviews Nature & Use Advantages Disadvantages
Questions can be predetermined, or created in response to answers. Design: structured/ unstructured questions Advantages Lots of ‘rich’ data Telephone interviews Disadvantages Social desirability bias, interview bias Requires skilled personnel Ethical Issues Confidentiality Privacy

19 Different types of self-report methods
EVALUATION: Different types of self-report methods Strengths Weaknesses Unstructured Interview Allows collection of rich, qualitative data Hard to compare responses Structured/ Semi-Structured interview Enable comparisons between participants responses Limit interviewees responses, so full information is not gained. Open ended questions Enable freedom to answer as they choose Makes statistical analysis difficult Close questions Enable collection of quantitative data and therefore make statistical analysis possible

20 EVALUATION: Self-Reports
Strengths Valuable method of investigating thoughts and feelings. Practical research method that enables collection of large amount of data. Measures are usually standardised and can be reproduced Can produce numerical data that can easily be analysed Weaknesses Self report is subjective and lacks scientific rigour Interviewing can be time consuming and not usually conducted on large samples It is not possible to gauge whether respondents are telling the truth in their responses. Requires respondents to recall events or feelings, which effects reliability.

21 PROCEDURE: Overview 5-7 marks 8-10 marks Good description of procedure
Good evaluation of procedure 2 strengths 2 weaknesses In-depth description of procedure, including use of specialist terms In-depth evaluation of procedure 3+ strengths 3+ weaknesses Good use of grammar and limited spelling mistakes. Describe (4 marks) Evaluate (6 marks) Type Timing (20 min) Who Location When (time of day) IV/DV Reliability Validity Ethics

22 PROCEDURE: Plan What the researcher is going to do step by step.
If it’s an observational method- what behaviour is going to be observed? Have you classified the behaviour and created a coding system? Have all the observers been chosen and given training on what behaviour to observe and record? How you chosen where the observation in going to be? Don’t forget your key terms- i.e. what type of experiment is it? - The strengths and weaknesses of that experiment type? Sampling method- strengths and weaknesses of your sampling method and anything which might affect your sample (Cohort effect). Single Blind/Double Blind procedure? Any type of control method such as counterbalancing for repeated measures design? What type of design in it? Inter rater reliability? Ecological Validity? Ability to generalise? How about any ethical issues which might need to be considered for the study? How might they affect the results? How might you deal with them? (Remember-brief/debriefing for a laboratory experiment?) Remember- relate all these to the experiment in question. Responses need to be in context. If the experiment is a laboratory experiment- include factors that affect laboratory experiments such as low Ecological validity which means it’s difficult to generalise outside a lab setting.

23 PROCEDURE: Self-Report
Decide aim and research question & hypothesis Identify research method being used Identify variables Plan procedure: obtain ethics approval, outline how you will carry out this research, give examples of questions Possibly run pilot study in order to check feasibility Outline details of how you will collect data If, appropriate, thank and debriefed pts Analyse data, produce findings and draw conclusions Write report of practical investigation
