Contribution of Authors
This Ph. D thesis consists of seven manuscripts. Specific for the second manuscript with
the title “The unique contribution of intolerance of uncertainty to social anxiety”, Mair Roberts
and Hannah Blowfield provided the archival data. I had a principle role in the development of
the study idea, definition of study questions, formulation of hypotheses, design and
methodology, data management, statistical analyses and interpretation of the findings, and
manuscript writing and revisions. For the other six manuscripts, I was responsible for the entire
process. My supervisors, Professor Mark H Freeston and Doctor Jacqui Rodgers, provided
guidance throughout.

Acknowledgements
I would like to express my gratitude to my supervisors, Professor Mark Freeston and Dr
Jacqui Rodgers, for their exceptional mentorship and sincere support throughout my studies.
The term “supervisor” does not encapsulate what they have given to me in terms of
accomplishing my study and the development of my personal character over the last few years,
particularly during a very challenging personal time. It was truly invaluable and I greatly
appreciate it.
I would also like to express my sincere appreciation to Dr Alison Tyson-Capper, Dr.
Fiona LeBeau, Dr Gabriele Jordan and Dr. Robert Dudley, for their support, suggestions and
encouragement. Furthermore my thanks go to all the gate keepers and participants both in the
UK and Indonesia for their assistance in data collection. I would also like to acknowledge the
contribution of archival data from the following undergraduate students: Mair Roberts and
Hannah Blowfield. I would also like to thank to my “supervisor-mates”: Alin, Khulood, Tim
and Nicola for their support, encouragement and ideas and furthermore to Michael Henderson
for the proof-reading.
I would like to express a sincere thank you to my parents. My prayers are always for
you and even though you are not here anymore, your love and guidance are always the light in
my life. To my sisters: mbak Yuyun, mbak Ana and Ningrum, for their unwavering support and
love.
A very special thank you goes to my beloved wife, Devy Erfasanti, who sincerely loved
me, unconditionally accepted me and sincerely supported me with her genuine love. Although
you are not with us any more, we will always love you and your love will always be in our
hearts. To my beloved daughter, Azzahra Melica Marzie, your eyes, smile and happiness always
strengthen me. No words can describe the love your mum and I have for you. I dedicated this
thesis to both of you.
