Conclusion

The first psychological study is concluded on the basis of views and experiences shared and data collected from recruited teenage mothers (research participants) in the qualitative research. Teenage mothers usually face a lot of issues while going through the time of pregnancy and the delivery of the baby. At times, they also suffer with serious illness, which usually include mental disorder, such as, depression and anxiety. Other biological disease includes high blood pressure and severe headache.

The second psychological study is concluded on the basis of two different therapy used and compared to deal with insomnia. The number of sleeping hours tends to vary according to the specific therapy applied. It signified the importance of CBT through the psychologist's prediction that the participants who received CB sleep for longer than those participants who received the aromatherapy. This theory revealed that CBT is more effective therapy than aromatherapy.

The third psychological study is concluded on the basis of the relationship between the number of hours a child spends watching TV and his or her reading age. The investigation of child's reading age showed that there is an ordinary relationship between the number of hours a child spends watching TV and his or her reading age, depending upon the nature, temperament, and mental intelligence of each child.

The fourth psychological study is concluded on the basis of a simple comparison between the proportions of male and female smokers. It showed that female smokers exist in larger proportion as compared to male smokers.
