Chapter 3.0 Research Methodology 3.1 Research design

The research design for this study is a quantitative and qualitative research using the MANOV A test to analyze the results of interacting behaviours portrayed by the mothers of both groups. Each session between the mother and child will be video recorded for about 25 minutes (only 5 middle minutes being utilized for data collection) because according to Pino (2000), this will allow more time for the mothers to begin interacting and to settle into the setting.

3.2 Population Study

Kelantanese Malay mothers-child dyads were employed in this study. The subjects were then divided equally into two groups of hearing mothers with impaired children and hearing mothers with normal-hearing children. The hearing-impaired children were recruited from the Audiology Clinic, Hospital Universiti Sains Malaysia and from Deaf Kids Excellence Centre Kelantan (D'KECEK), Pusat Pengajian Sains Kesihatan, USM. The duration for the data collection was 2 months, starting from January 2011 to February 2011. All hearing-impaired children were diagnosed by a certified audiologist as having severe to profound sensorineural hearing loss bilaterally. In the other sample, the children of normal-hearing were recruited from IQ Islam Tadika, Kubang Kerian. All normal-hearing children had no reports of visual and hearing disabilities. Please refer to Figure 3.1 for the flowchart of the study.

3.3 Sample size

The age-range for the participants is from 3 :0 to 5: 11 years old. The sampling size of this research, it is based on the study of Pino (2000). The sample size was calculated based on the following information: significance level of 0.05, power of study of 0.8, mean difference of 2.83, standard deviation 1 of 2.45 and standard deviation 2of1.5. Using the "comparison of two means" option in Medcalc software (www.medcalc.be), the sample size required is 9 for each group (a total of 18 subjects).

3.4 Inclusion criteria

Participants will be chosen based on the inclusion criteria for this research which is Kelantanese Malay mothers raised and born in Kelantan with children aged 3:0 to 5:11 years old age born and raised in Kelantan. Child must have either normal-hearing or normal-hearing-impaired (severe to profound sensorineural normal-hearing loss bilaterally).

The child must be having severe to profound hearing loss because according to Cross et. al. (1980), the child with only residual hearing will have a more significant effect on the mother's behaviour in responding during mother-child interaction because their child's hearing ability is not within the speech sounds frequencies. For the hearing impaired children, they must be wearing hearing aids bilaterally. Also both mother and child dyad must be healthy.

3.5 Exclusion criteria

Participants will not be chosen if the hearing-impaired children are not wearing hearing aids bilaterally or if the child acquired hearing loss not due to congenital factor. For mothers who are not born and raised in Kelantan will be

excluded from the study. If the mother had moved or studied overseas for a period of time, they too will be excluded from the study. For the mothers who married with a non-Kelantanese husband will also be excluded from the study. If the child's aged is not within 3:0 to 5:11 years old, they will not be allowed to participate in this study.

Any medical complications besides hearing loss in the child will be excluded from the study and any health problems in the mothers will also be excluded from the study.

3.6 Instrument

The research tools that will be used in this study are a Sony Camera Video Recorder to recorder the mother-child interaction for 25 minutes. A selection of toys for the session will be given to the mothers to play with their children and the same set of toys was used in all the session for all mother-child dyads. A list of the selected toys can be found in Table 3.1. A checklist will be used by the researcher during the mother-child interaction and its categories is based on Pino (2000) which were adopted and modified for this study (refer Table 3.2 or Appendix 1 and 2).

Chapter 3.0 Research Methodology 3. 7 Study location

All the sessions recorded will be conducted inside a room at the Tadika IQ Islam and in the Klinik Bahasa-Pertuturan, Pusat Pengajian Sains Kesihatan as the natural setting instead of at home. The main bias that will arise in this observation is that the room setting in the kindergarten and the clinic will not fully portray out the mother's and child's behaviour due to the different setting, where initially, they are used to their own home setting. However according to Beckwith (1996), it is stated that setting the clinic or any other place as the natural setting for the parent child observation perturb the ordinary routines in the belief that adapting to perturbations is more revealing of individual differences than reacting to familiarity. This condition suggests that the researcher will have a better observation of the behaviours exhibited during the mother child interaction as they will be more revealing in their behaviours during the session, in an outside environment from their home setting.

3.8 Study procedure

All subjects was selected base on the inclusion criteria and after that, consent will be taken from mothers for video recording of the session. Mothers will be asked to, 'just play with your child the way you usually do". No further instruction will be given to the mothers throughout the video recording session. The mothers will be told to ignore the researcher as much as possible. The mothers are also required to maintain typical communication patterns with their child and conversation directed toward to researcher is discouraged. During the video recording, the dyads will be required to maintain their interaction within the scope of the camera. The video recording will last for 25 minutes and only the middle 5 minutes will be chosen for analyzing the mother's portrayed behaviours. Mother's behaviour will be analyzed
